Why Professional Email Matters

Free vs. Professional Email

Free email (Gmail, Yahoo, Outlook.com):

john.smith123@gmail.com
mybusiness2024@yahoo.com
startup_email@outlook.com

Problems:

• Looks unprofessional
• Not memorable (numbers, underscores)
• No brand reinforcement
• Limited control
• Can't customize
• Trust issues from customers

Professional email (custom domain):

john@yourbusiness.com
info@yourbusiness.com
support@yourbusiness.com

Benefits:

• Professional appearance
• Brand reinforcement (every email markets your domain)
• Memorable addresses
• Full control
• Unlimited addresses
• Builds trust
• Portable (switch providers, keep addresses)

Impact on business:

• Trust: Customers trust john@company.com vs. john_company@gmail.com
• Branding: Every email reinforces your brand
• Professionalism: Serious businesses have professional email
• Credibility: Required for many business applications

Cost: $6-20/user/month typically

ROI: First customer gained due to professional appearance pays for years of email

Email Setup Options

Setting Up Email Addresses

Common Email Addresses to Create

Essential (create first):

admin@yourdomain.com

• Domain management
• Service signups
• Internal use

info@yourdomain.com

• General inquiries
• Contact form submissions
• Public-facing

support@yourdomain.com

• Customer support
• Help requests
• Ticket system

sales@yourdomain.com

• Sales inquiries
• Lead capture
• Business development

Yourname@yourdomain.com

• Personal email
• Direct communication
• Professional correspondence

Additional (as needed):

billing@yourdomain.com

• Invoicing
• Payment inquiries
• Accounting

hello@yourdomain.com

• Friendly alternative to info@
• Modern, approachable

team@yourdomain.com

• Internal team communication
• Newsletters to team

noreply@yourdomain.com

• Automated emails
• Newsletters
• Transactional emails

Group addresses:

• marketing@
• hr@
• legal@
• design@
• dev@

Department-specific:

• firstname.lastname@yourdomain.com

Best practices:

• Create role-based addresses (info@, support@)
• Use groups for team addresses
• Avoid numbers in professional addresses
• Keep it simple and memorable
• Use aliases to direct multiple addresses to one inbox

Email Aliases vs. Mailboxes

Mailbox (costs money):

john@yourdomain.com
- Separate inbox
- Separate login
- Costs $6/month (Google Workspace)
- Can send and receive independently

Alias (free):

j.smith@yourdomain.com → forwards to john@yourdomain.com
johnsmith@yourdomain.com → forwards to john@yourdomain.com
sales@yourdomain.com → forwards to john@yourdomain.com
- Same inbox as john@
- No separate login
- Free
- Can send as alias

Use aliases to:

• Create multiple email addresses without paying for mailboxes
• Direct different purposes to same inbox (sales@, info@ → you)
• Provide multiple formats of your name
• Track which address is used (sales@ vs info@)
• Create temporary addresses for specific purposes

Example efficient setup:

3 paid mailboxes ($18/month Google Workspace):

1. john@yourdomain.com (owner)
2. sarah@yourdomain.com (marketing)
3. mike@yourdomain.com (support)

10+ free aliases:

• info@ → john@
• hello@ → john@
• sales@ → john@
• admin@ → john@
• marketing@ → sarah@
• design@ → sarah@
• support@ → mike@
• help@ → mike@
• billing@ → john@
• team@ → john@, sarah@, mike@ (group)

Result: Professional email presence with 10+ addresses for $18/month

Email Configuration

DNS Records for Email

Required records:

MX Records (Mail Exchange)

Purpose: Directs incoming email to mail server
Example (Google Workspace):
Type: MX
Host: @
Priority: 1
Value: ASPMX.L.GOOGLE.COM

SPF Record (Sender Policy Framework)

Purpose: Prevents email spoofing
Example:
Type: TXT
Host: @
Value: v=spf1 include:_spf.google.com ~all

Why important:

• Tells receiving servers your domain allows Google to send email
• Without it, emails may go to spam
• Authentication mechanism

DKIM Record (DomainKeys Identified Mail)

Purpose: Email signature verification
Example:
Type: TXT
Host: google._domainkey
Value: [long key from Google]

Setup:

• Generated by email provider
• Copy from provider dashboard
• Add to DNS
• Enables email authentication

DMARC Record (Domain-based Message Authentication)

Purpose: Email authentication policy
Example:
Type: TXT
Host: _dmarc
Value: v=DMARC1; p=quarantine; rua=mailto:admin@yourdomain.com

What it does:

• Tells receiving servers what to do with unauthenticated email
• p=quarantine: Put suspicious email in spam
• p=reject: Reject unauthenticated email
• p=none: Monitor only (for testing)

Full email DNS setup (Google Workspace example):

MX Records:
1. ASPMX.L.GOOGLE.COM (priority 1)
2. ALT1.ASPMX.L.GOOGLE.COM (priority 5)
3. ALT2.ASPMX.L.GOOGLE.COM (priority 5)
4. ALT3.ASPMX.L.GOOGLE.COM (priority 10)
5. ALT4.ASPMX.L.GOOGLE.COM (priority 10)

SPF Record:
v=spf1 include:_spf.google.com ~all

DKIM Record:
google._domainkey → [key from Google]

DMARC Record:
_dmarc → v=DMARC1; p=quarantine; rua=mailto:admin@yourdomain.com

DNS propagation:

• MX records: 1-24 hours
• SPF/DKIM/DMARC: 1-48 hours
• Full email functionality: Allow 48 hours max

Testing email DNS:

• MX Toolbox (mxtoolbox.com)
• Google Admin Toolbox
• Mail-tester.com (send test email)

Email Client Setup

Email clients:

• Gmail web interface
• Outlook web
• Apple Mail (Mac, iPhone)
• Outlook desktop (Windows)
• Thunderbird (cross-platform)
• Mobile apps (iOS Mail, Android Gmail)

IMAP vs POP3:

IMAP (recommended):

• Syncs across all devices
• Email stays on server
• Read on phone, still unread on laptop
• Folders sync
• Modern standard

POP3 (old, avoid):

• Downloads to single device
• Removes from server
• No sync
• Outdated

Settings needed:

IMAP (incoming) example (Google Workspace):

Server: imap.gmail.com
Port: 993
Security: SSL/TLS
Username: john@yourdomain.com
Password: [your password or app password]

SMTP (outgoing) example (Google Workspace):

Server: smtp.gmail.com
Port: 587 or 465

Your Business Name

📧 john@yourbusiness.com
🌐 www.yourbusiness.com
📞 +1 (555) 123-4567

[Optional: Social media icons/links]
[Optional: Company logo]

Don'ts:

• Projects
• Archive
• Follow-up
• Waiting for reply

Filters/rules:

• Auto-label emails from specific senders
• Auto-archive newsletters
• Auto-forward certain emails
• Flag important contacts

Keep inbox clean:

• Inbox Zero philosophy
• Process emails, don't let pile up
• Archive old emails
• Delete unnecessary

Search, don't file:

• Modern email search is excellent
• Don't over-organize
• Archive and search when needed
• Tags/labels better than complex folders

Security

Enable 2FA:

• Google Workspace: Admin enforces
• Personal account: Settings → Security → 2FA

Use strong passwords:

• Unique for email
• 16+ characters
• Password manager
• Changed regularly

Be cautious:

• Phishing emails (verify sender)
• Suspicious links (hover before clicking)
• Attachments from unknowns (don't open)
• Too-good-to-be-true offers

Email encryption (if needed):

• ProtonMail (built-in encryption)
• PGP/GPG (advanced)
• Encrypted file sharing (for attachments)
