Good Email Address: 7 Rules & 5 Examples 2026
Email address example list: 55+ copy-ready formats for personal, professional, shared-inbox, and department use — plus 7 rules for what makes one good.
A good email address immediately signals who you are or what your business does. It is readable, professional, and easy to remember — and for business use, it always uses a custom domain rather than a free provider. This guide is an email address example list organized by type — covering personal, professional, shared inbox, and department formats — along with the seven rules that define what makes one good.
What is a good email address? A good email address uses your real name or a clear function (like info@ or support@), ends in your own domain rather than a free provider, contains no unnecessary numbers or symbols, and is short enough to say aloud. For business: firstname@company.com. For personal use: firstname.lastname@gmail.com.

Good Email Address at a Glance (2026)
| Criterion | Good | Bad |
|---|---|---|
| Domain | @yourcompany.com |
@gmail.com (for business) |
| Local part | john.smith |
js19872006 |
| Length | Under 20 chars | customer.contact.2024_main |
| Numbers | Only if part of name | sarah123 |
| Symbols | One dot or hyphen | sarah__m..doe |
| Speakable | Easy to say aloud | Must spell out every character |
A good email address is short, readable, tied to a real identity, and — for business — uses a custom domain. Everything else follows from those four criteria.

What Makes a Good Email Address?
A good email address is one that is readable, professional, and clearly tied to a real person or business function. It uses a custom domain for business communication, avoids unnecessary numbers and symbols, and is short enough to say out loud without spelling it out.
The qualities of a good email address:
- Readable at a glance — Use dots or underscores to separate words.
john.smith@company.comis clearer thanjohnsmith123@company.com. - No unnecessary numbers — Avoid numbers unless they are part of your actual name. Numbers make an address look like a fallback rather than a deliberate choice.
- Short and speakable — If you would have to spell it out on a phone call, it is too long. The ideal address is under 20 characters in the local part.
- Custom domain for business — For any business use,
@yourcompany.comis always better than@gmail.comor@yahoo.com. A custom domain signals legitimacy and improves email deliverability. - No random characters or symbols — Hyphens and underscores are allowed, but use them sparingly. Consecutive dots, leading/trailing dots, and spaces are invalid and look unprofessional.
- Tied to a real identity or function — A good business email either matches a person's name (
sarah@company.com) or a clear role (support@company.com). Ambiguous addresses likeaccounts2b@domain.comundermine trust.
Good vs. bad email address examples:
| Good | Bad | Why |
|---|---|---|
john.smith@gmail.com |
js19872006@gmail.com |
Numbers and initials look impersonal |
sarah@acmecorp.com |
sarah@gmail.com (for business) |
Free domain signals personal, not professional |
info@company.com |
info_company_main@gmail.com |
Too long, underscores, free domain |
hello@yourbrand.com |
hello1@yourbrand.com |
Unnecessary number implies an afterthought |
support@startupname.io |
cust.support.2024@yahoo.com |
Clear role vs. cluttered fallback |
The single most important rule: use your own domain for any business email. Everything else is secondary. A clean firstname@yourdomain.com beats a messy @gmail.com address every time.
Good Email Address: Quick Checklist
Use this checklist before finalizing any email address:
- Readable at a glance — Uses a dot or underscore to separate words. No ambiguous characters.
- Short enough to say aloud — The local part (before @) is under 20 characters.
- No unnecessary numbers — Numbers only appear if they are part of your actual name.
- Custom domain for business — Ends in
@yourcompany.com, not@gmail.comor@yahoo.com. - No random symbols — Only dots (
.), hyphens (-), or underscores (_) where needed to separate words. - Tied to a real identity or function — Matches a person's name (
sarah@company.com) or a clear role (support@company.com). - Consistent with your team — Follows one format (
firstname@orfirstname.lastname@) across all employees.
A good email address passes all seven checks. If any of these fails, revise the address before using it in business communications.
Email Address Example List: Quick Picks by Situation
If you only need an email address example list to copy from, start here. Pick the line that matches your situation, then swap in the domain you actually own. The best choice is usually the address customers can understand without asking what it means.
| Situation | Good Email Address Examples | Why It Works |
|---|---|---|
| Restaurant | reservations@riversbistro.com, catering@riversbistro.com, hello@riversbistro.com |
Separates table requests, event inquiries, and general questions |
| Service business | bookings@ridgeviewplumbing.com, support@ridgeviewplumbing.com, billing@ridgeviewplumbing.com |
Routes urgent jobs, customer help, and payment questions to the right place |
| E-commerce store | support@northtrailgear.com, returns@northtrailgear.com, wholesale@northtrailgear.com |
Gives shoppers clear paths for orders, returns, and bulk buyers |
| Healthcare office | appointments@greenvalleyclinic.com, billing@greenvalleyclinic.com, records@greenvalleyclinic.com |
Keeps scheduling, payments, and document requests separate |
| Hotel | reservations@harborinn.com, frontdesk@harborinn.com, events@harborinn.com |
Matches the way guests already think about hotel requests |
| SaaS company | support@brightdesk.io, billing@brightdesk.io, security@brightdesk.io |
Covers help tickets, invoices, and responsible security reports |
Restaurant: A restaurant should use role-based addresses because customers usually need a fast answer about a table, catering order, private event, or lost item. reservations@riversbistro.com is better than sending every message to a personal owner inbox because the purpose is clear before anyone opens the email. If the restaurant gets catering requests every week, give catering its own address instead of making staff dig through the general inbox.
Service business: Plumbers, electricians, HVAC companies, cleaners, and landscapers get a mix of new job requests, repeat customer questions, and invoice follow-ups. bookings@ridgeviewplumbing.com works well for new appointments, while support@ or service@ fits existing customers who need help. Keep billing@ separate so payment questions do not get buried under emergency requests.
E-commerce: Online stores should make the next step obvious for the shopper. support@northtrailgear.com covers order questions, returns@northtrailgear.com handles exchanges, and wholesale@northtrailgear.com gives larger buyers a direct path. Avoid clever names for these inboxes; people looking for a refund or shipment update want clarity, not personality.
Healthcare: Clinics and wellness offices should keep addresses plain and specific. appointments@greenvalleyclinic.com, billing@greenvalleyclinic.com, and records@greenvalleyclinic.com tell patients where to send each request without exposing private details in the address itself. Do not put diagnoses, treatments, or patient identifiers in a public-facing email address.
Hotel: Hotels benefit from email addresses that match common guest needs. reservations@harborinn.com is easy to remember for booking questions, frontdesk@harborinn.com fits day-of-stay help, and events@harborinn.com is clear for weddings or meetings. If one team watches all three inboxes, the separate names still make sorting and response priority much easier.
SaaS company: Software companies usually need more than one shared inbox because customers, finance teams, and security researchers all write for different reasons. support@brightdesk.io should handle product questions, billing@brightdesk.io should handle invoices, and security@brightdesk.io gives vulnerability reports a safe place to land. As the company grows, add status@ or updates@ only if someone is assigned to monitor replies.
Email Address Example List: More Industries and Scenarios
The quick picks above cover the most common business situations. This extended email address example list covers industries with their own naming conventions or requirements that did not fit the tables above.
Real Estate
| Role | Email Address Example |
|---|---|
| Agent | sarah.jones@coastalproperties.com |
| Property management | rentals@harborpm.com |
| Listings inquiries | listings@citywidegroup.com |
| General office | hello@premierrealty.com |
| Closings and title | closings@titlegroup.com |
Real estate agents use their full name (sarah.jones@) so clients can search and verify them. Team inboxes like listings@ or rentals@ handle shared workloads without confusion — the subject is obvious before anyone opens the email.
Education
| Role | Email Address Example |
|---|---|
| University student | sjones@student.university.edu |
| Faculty member | prof.chen@university.edu |
| Admissions office | admissions@college.edu |
| K–12 teacher | s.johnson@schooldistrict.org |
| Tutoring service | bookings@tutorright.com |
Most universities issue addresses in firstname.lastname@school.edu or flastname@school.edu format. Public schools default to first.last@schoolname.org. Neither uses free providers for official communication — the institutional domain carries weight that a @gmail.com address doesn't.
Nonprofits
| Role | Email Address Example |
|---|---|
| General contact | info@communityreach.org |
| Donations | donate@giveforward.org |
| Volunteers | volunteers@helplocal.org |
| Executive director | ed@nonprofitname.org |
| Programs team | programs@missiondriven.org |
Nonprofits use .org domains. A dedicated donate@ or giving@ address keeps financial contributors separate from general queries — development teams should not miss donation-related emails buried in an info@ inbox that receives everything.
Financial Services and Accounting
| Role | Email Address Example |
|---|---|
| CPA or accountant | david.chen@taxservices.com |
| Client intake | clients@advisorygroup.com |
| Accounts and billing | accounts@cpagroup.com |
| Compliance | compliance@wealthco.com |
| General inquiries | info@planninggroup.com |
Finance firms use conservative formats — individual advisors get firstname.lastname@, shared inboxes get function names (accounts@, compliance@). In this industry, the email address itself signals formality before a single word of the message lands.
Content Creators and Podcasters
| Role | Email Address Example |
|---|---|
| Brand partnerships | partnerships@podcastname.com |
| Guest bookings | guests@showname.com |
| Press inquiries | press@creatorname.io |
| Newsletter | newsletter@yourbrand.com |
| Audience contact | hello@contentsite.com |
Separating partnerships@ from hello@ tells potential sponsors there is a real business contact point. Mixing the two inboxes makes it easy to lose high-value outreach under fan mail. A simple two-address setup handles almost every creator's volume.
Email Address Example List by Purpose
Most people searching for an email address example list want examples for a specific job — not just examples of name formats. Here are 40+ examples organized by what the address is actually used for.
Sales Outreach and Lead Generation
| Purpose | Email Address Example |
|---|---|
| Sales rep (individual) | sarah.jones@company.com |
| General sales team | sales@company.com |
| SDR team | outreach@company.com |
| Partnerships | partners@company.com |
| Business development | bizdev@company.com |
For outbound sales, individual addresses (sarah.jones@) outperform generic sales@ inboxes because recipients can look up who is writing. Cold email from a role inbox reads as mass outreach; the same message from a named address reads as personal contact.
Customer Onboarding and Welcome Emails
| Purpose | Email Address Example |
|---|---|
| Onboarding team | onboarding@company.com |
| Account setup | setup@platform.io |
| Welcome sequence | welcome@yourbrand.com |
| Success team | success@company.com |
| Activation | start@appname.io |
Onboarding emails benefit from a warm From address. welcome@yourbrand.com is more inviting than noreply@platform.io — even though both are automated, the address signals that someone might actually read a reply.
Transactional and System Emails
| Purpose | Email Address Example |
|---|---|
| Order confirmations | orders@shopname.com |
| Shipping notifications | shipping@shopname.com |
| Password reset | noreply@platform.com |
| Invoices | billing@company.com |
| Receipts | receipts@service.com |
| Notifications | notifications@appname.io |
Transactional addresses should use noreply@ only when no reply is actually expected or useful. For invoices and shipping, a real inbox (billing@, shipping@) is better — customers with questions need somewhere to write back.
Marketing and Newsletter Emails
| Purpose | Email Address Example |
|---|---|
| Newsletter | newsletter@yourbrand.com |
| Weekly digest | weekly@publication.com |
| Promotions | hello@shopname.com |
| Product updates | updates@platform.io |
| Announcements | news@company.com |
For newsletters and marketing emails, hello@yourbrand.com consistently outperforms marketing@ as a From address because it feels like a message from a person rather than a department. The address affects open rate before the subject line does.
Security, Legal, and Compliance
| Purpose | Email Address Example |
|---|---|
| Security disclosures | security@company.com |
| Abuse reports | abuse@platform.com |
| Legal notices | legal@company.com |
| Privacy requests | privacy@company.com |
| Compliance | compliance@firm.com |
Security and legal addresses should match the exact industry convention. security@company.com is the expected address for vulnerability disclosures — security researchers and bug bounty platforms default to it. Deviating from this format means missing reports.
Hiring and Recruiting
| Purpose | Email Address Example |
|---|---|
| Job applications | careers@company.com |
| Active recruiting | hiring@company.com |
| HR team | hr@company.com |
| Recruiter (individual) | tom.reed@company.com |
| Campus recruiting | campus@company.com |
Hiring emails get better response rates from individual recruiter addresses. A candidate deciding whether to open a message from tom.reed@company.com versus careers@company.com will engage more with the named sender — it feels less like an automated funnel and more like someone who found their profile.
Press, PR, and Media Relations
| Purpose | Email Address Example |
|---|---|
| Media inquiries | press@company.com |
| PR contact | pr@company.com |
| Analyst relations | ar@company.com |
| Investor relations | ir@company.com |
| Speaking requests | speaking@company.com |
Journalists and analysts look for press@ as the default media contact address. This is close to universal — most style guides for journalists recommend checking the company website for press@ or media@. Having neither means press inquiries get lost in info@.

What Are the 5 Examples of Email Addresses?
An email address has two parts: the local part (before the @) and the domain (after the @). Every valid email address follows the format localpart@domain.com. Beyond that basic structure, there are several common formats used in personal, professional, and business contexts.
Here are the five most widely used types, with concrete examples of each.
1. Personal Email Address
Format: firstname.lastname@provider.com
Examples:
john.smith@gmail.commaria.garcia@outlook.comalex.johnson@yahoo.com
A personal email address is tied to a free consumer provider like Gmail, Outlook, Yahoo, or iCloud. The most common format uses your first and last name separated by a dot, which keeps it readable and easy to remember.
Variations:
j.smith@gmail.com(initial + last name)jsmith1987@gmail.com(name + birth year, when name is taken)john_smith@gmail.com(underscore separator)
When to use it: Personal communication, signing up for services, keeping in touch with friends and family. A personal email address works fine for individuals, but looks informal in business settings.
2. Professional Work Email Address
Format: firstname@company.com or firstname.lastname@company.com
Examples:
sarah@acmecorp.comdavid.chen@techstartup.ior.williams@lawfirm.com
A professional work email uses a company-owned domain instead of a free provider. This is the standard format for employees at any organization. It signals legitimacy — both to external contacts and to search engines (important for deliverability and trust).
Variations:
dchen@company.com(first initial + last name)david.c@company.com(first name + last initial)david.chen.sales@company.com(name + department, for larger organizations with duplicate names)
When to use it: All business communication, outreach, and customer-facing correspondence. A custom domain email (@yourcompany.com) immediately conveys that you are a real business, not an individual with a free account.
3. Role-Based Email Address
Format: role@company.com
Examples:
info@acmecorp.comsupport@techstartup.iohello@smallbusiness.comcontact@agency.comnoreply@platform.com
A role-based email is not tied to one specific person. It represents a function or general point of contact. These are the most commonly displayed email addresses on websites, business cards, and customer communications.
Common role-based formats:
| Address | Typical Use |
|---|---|
info@ |
General inquiries |
support@ |
Customer service and help tickets |
hello@ |
Friendly, general-purpose contact |
contact@ |
Website contact forms |
admin@ |
Administrative or internal use |
noreply@ |
Automated outgoing messages |
billing@ |
Invoice and payment questions |
press@ |
Media and PR inquiries |
When to use it: Any email address displayed publicly that multiple team members might monitor or respond to. Role-based addresses survive staff changes — when your support lead leaves, support@company.com keeps working without confusing customers.
4. Department or Team Email Address
Format: department@company.com
Examples:
sales@acmecorp.comhr@techstartup.iomarketing@agency.comfinance@company.comlegal@lawfirm.com
Department email addresses work similarly to role-based addresses but are organized around internal business units rather than customer-facing functions. They are shared inboxes monitored by an entire team.
Examples by department:
sales@— lead inquiries, quotes, and deal correspondencehr@— job applications, employee questions, benefitsmarketing@— partnerships, sponsorships, vendor outreachoperations@— logistics, vendor managementfinance@oraccounts@— invoicing and paymentslegal@— contracts and compliance
When to use it: Any team that needs a shared inbox for routing incoming messages. Department addresses are especially useful for businesses growing beyond a handful of people where individual email routing becomes unmanageable.
5. Branded or Custom Email Address
Format: word@brand.com (non-name, non-role identifier)
Examples:
hello@hifivestar.comteam@yourbrand.comhi@modernstartup.ioask@consultfirm.comjoin@community.org
Branded custom email addresses use deliberately chosen words that reflect a brand's personality — friendly, approachable, or premium — rather than a generic role or personal name. They are common in startups, agencies, and consumer brands that want their email address to feel intentional rather than default.
Variations by brand voice:
- Friendly:
hello@,hi@,hey@ - Professional:
team@,office@,studio@ - Action-oriented:
ask@,connect@,start@ - Community:
join@,members@,community@
When to use it: When your brand has a distinct personality and you want every customer touchpoint — including the From address on emails — to reflect it. A startup sending from hello@freshco.com feels more alive than one sending from contact@freshco.com.
How to Choose the Right Email Address Format
The right format depends on who is sending and why:
| Situation | Recommended Format |
|---|---|
| Personal use | firstname.lastname@gmail.com |
| Solo business owner | firstname@yourbusiness.com |
| Small team (shared inbox) | info@ or hello@yourbusiness.com |
| Specific department | sales@ / support@ / hr@company.com |
| Brand with personality | hello@ or hi@yourbrand.com |
| Automated transactional | noreply@ or notifications@company.com |
The single most important rule: use a custom domain for any business communication. Free email providers (@gmail.com, @yahoo.com) are associated with personal use. Customers and partners trust emails from @yourcompany.com significantly more — and email deliverability improves when you own your sending domain.
Good Email Address for Gmail: Personal Format Guide
When you need a good Gmail address (for personal or freelance use), the same rules apply — just with @gmail.com instead of a custom domain.
Best Gmail formats for a good email address:
| Format | Example | Notes |
|---|---|---|
| First + Last | john.smith@gmail.com |
Best: clear, professional, easy to remember |
| First + Middle initial + Last | john.a.smith@gmail.com |
Good if first/last is taken |
| First initial + Last | j.smith@gmail.com |
Compact; works well for common names |
| First name only | johncsmith@gmail.com |
Only if name is naturally unique |
Avoid in a Gmail address:
- Birth years (
jsmith1987@gmail.com) — makes it look like a throwaway account - Random numbers (
john44821@gmail.com) — signals the name was already taken many times - Underscores and consecutive dots — technically valid but dated-looking
- Nicknames that don't match your real name
When your preferred Gmail address is taken:
Try firstname.middleinitial.lastname@gmail.com or firstname.lastname.location@gmail.com (like john.smith.chicago@gmail.com) before resorting to numbers. A name-based address always looks more credible than one with a random number suffix.
For business use, switch to a custom domain as soon as possible. Even a freelancer benefits from firstname@yourdomain.com over yourname123@gmail.com when pitching clients.
How to Create a Good Email Address
Creating a good email address takes less than five minutes once you know what to include — and what to avoid.
Step 1: Get your own domain. Register yourbusiness.com or yourname.com through a registrar (Google Domains, Namecheap, or Cloudflare Registrar are reliable options). Without a custom domain, your email address is capped at "good enough for personal use" at best.
Step 2: Choose your format. For individuals: firstname@ or firstname.lastname@. For shared inboxes: info@, support@, or hello@. For departments: sales@, hr@, or marketing@.
Step 3: Keep it short. Count the characters in the local part (before @). Aim for under 20 characters — ideally under 15. If firstname.lastname puts you over, use first initial plus last name (for example, j.smith@) instead.
Step 4: Use only dots or hyphens to separate words. Avoid underscores (_) where possible — they are technically valid but look dated and can appear as spaces in some email clients.
Step 5: Test it out loud. Say the address on an imaginary phone call. If you would have to spell it out letter by letter, it is too complicated. The goal is an address someone can hear once and type correctly.
A good email address takes about five minutes to set up and pays off in every customer interaction and business communication that follows.
Email Address Examples: What Makes One Valid?
A valid email address must follow this structure:
localpart@domain.extension
The local part (before @) can contain:
- Letters (a–z, A–Z)
- Numbers (0–9)
- Dots (.), underscores (_), hyphens (-)
- Must not start or end with a dot
The domain (after @) must be:
- A valid registered domain
- Includes at least one dot (like
.com,.org,.io)
Invalid email examples:
john@— missing domain@gmail.com— missing local partjohn smith@gmail.com— space not allowedjohn..doe@gmail.com— consecutive dots not allowedjohn.@company.com— dot at end of local part
Good Email Address Examples by Industry
The best email format depends partly on your industry's conventions. Here are concrete examples of good email addresses across common business types — each following the same core principle: custom domain, clear identity, no unnecessary clutter.
Restaurant and Food Service

Common Email Address Mistakes to Avoid
Knowing what makes a good email address is easier when you see what makes a bad one. These are the five most common mistakes that make an address look unprofessional or undermine trust.
1. Using a free consumer domain for business
john@gmail.com works fine for personal email. For business, it signals you have not invested in your own domain — and customers and business partners notice.
Fix: Switch to john@yourbusiness.com. Google Workspace and Microsoft 365 let you use your own domain with the same Gmail or Outlook interface you already know.
2. Using birth years or random numbers
sarah1989@company.com or smith44821@gmail.com signals that the name was taken and the user resorted to padding. Neither impression helps your credibility.
Fix: Use firstname.lastname@domain.com or add a middle initial (s.a.smith@domain.com) instead of a birth year or random number.
3. Making the address too long
customer.relations.dept.main@yourbusiness.com is impossible to give over the phone and error-prone to type. Every extra character raises the chance of a bounce.
Fix: Keep the local part under 20 characters. Use crm@ instead of customer.relations.management@.
4. Using underscores or consecutive symbols
john__smith@domain.com or info..contact@company.com looks like a typo and is harder to read. Some legacy email systems also handle underscores inconsistently.
Fix: Use dots only. john.smith@domain.com is cleaner than john_smith@domain.com in almost every context.
5. Using nicknames or informal handles in professional addresses
big_boss@company.com or coolceo@brand.com may feel playful internally but reads as unprofessional to customers and partners who don't share the context.
Fix: Reserve informal handles for internal communication. Any customer-facing or partner-facing email should be name-based (sarah@) or role-based (support@).
A good email address avoids all five of these patterns. If your current address fails more than one check, the fix is simple: register your own domain and create a clean address before it affects how your business is perceived.
Why Business Email Addresses Matter for Customer Trust
When a business sends customer-facing messages — review requests, receipts, follow-ups — the From address is part of the impression. A customer receiving a review request from info@yourrestaurant.com is more likely to open and respond than one from jsmith1994@gmail.com.
At HiFiveStar, businesses send review requests with their business name as the sender, and can automate that workflow on Pro. When customers receive a branded, professional email asking for a Google review, open rates and response rates both improve. The email address is not just a technical detail — it is a trust signal at the moment it matters most.
HiFiveStar automates review requests via both email and SMS (on Pro), with your business name as the sender, so every outgoing message reinforces your brand rather than undermining it.
Frequently Asked Questions
What is a good email address?
A good email address is readable, memorable, and clearly tied to a real person or business function. The key qualities: no unnecessary numbers or random characters; a short local part (under 20 characters); dots or underscores used sparingly to separate words; and — for any business use — a custom domain (@yourcompany.com) rather than a free consumer provider. For personal use, firstname.lastname@provider.com is the gold standard. For business, firstname@yourbusiness.com or info@yourbusiness.com immediately convey legitimacy and trust.
What are 5 examples of email addresses?
Five common examples of email addresses across different contexts:
john.smith@gmail.com— personal email using name plus free providersarah@acmecorp.com— professional work email using first name plus company domaininfo@acmecorp.com— role-based general business emailsales@acmecorp.com— department email for a business teamhello@yourbrand.com— branded custom email for a consumer-facing business
What is a professional email address example?
A professional email address uses your name or role with a company domain rather than a free consumer email provider. Examples include david.chen@company.com, info@businessname.com, and support@startupname.io. Avoid addresses with nicknames, birth years, or free domains like @gmail.com in professional business correspondence.
Can a business use Gmail for email?
Technically yes, but Google Workspace (formerly G Suite) allows businesses to use Gmail with a custom domain — so you get Gmail's interface while sending from you@yourbusiness.com. This is much better than using a personal @gmail.com address for business, as it maintains deliverability, brand trust, and the ability to add team members under the same domain.
What are role-based email addresses?
Role-based email addresses are shared business inboxes that represent a function rather than an individual person. Common examples include info@, support@, sales@, hello@, billing@, and noreply@. They are useful because they do not need to change when staff do, and they can be monitored by multiple team members simultaneously.
How many types of email addresses are there?
Email addresses broadly fall into five categories: personal (tied to an individual and free provider), professional work (name plus company domain), role-based (function plus company domain), departmental (team plus company domain), and branded custom (intentional word plus brand domain). All follow the same technical format — localpart@domain — but serve different communication purposes.
What is a good email address for a business?
For a business, a good email address uses a custom domain (@yourbusiness.com) rather than a free consumer provider, and represents either a real person (sarah@company.com) or a clear function (support@company.com). The most professional format for individuals is firstname@yourdomain.com or firstname.lastname@yourdomain.com. For shared inboxes, info@, hello@, or support@ followed by your domain are strong choices — easy for customers to remember and credible to new contacts.
What should you avoid in an email address?
Avoid free providers (@gmail.com, @yahoo.com, @hotmail.com) for business use, random numbers that are not part of your name, consecutive underscores or hyphens, and local parts longer than 20 characters. An address like biz.contact.2024_main@gmail.com raises immediate credibility concerns — it looks accidental rather than intentional. The cleaner and more deliberate the address, the better the first impression it makes on customers, partners, and email spam filters alike.
