SMTP/IMAP Integration Integration
Connect Any Email Provider via SMTP and IMAP
Universal Email Provider Support
Not everyone uses Gmail or Outlook. WarmySender's SMTP/IMAP integration allows you to connect virtually any email provider—from major hosting companies to custom mail servers.
Common providers that work via SMTP/IMAP:
- GoDaddy Email
- Namecheap Email Hosting
- Zoho Mail
- Rackspace Email
- FastMail
- ProtonMail Bridge
- Custom mail servers (Postfix, Dovecot, etc.)
Finding Your SMTP/IMAP Settings
To connect via SMTP/IMAP, you'll need:
- SMTP Server: Usually smtp.yourdomain.com or mail.yourdomain.com
- SMTP Port: 587 (TLS) or 465 (SSL) or 25 (unencrypted)
- IMAP Server: Usually imap.yourdomain.com
- IMAP Port: 993 (SSL) or 143 (TLS)
- Username: Your full email address
- Password: Your email password or app-specific password
Your hosting provider's documentation will have these details, or contact their support.
Security Considerations
When using SMTP/IMAP connections:
- Always use TLS or SSL encryption when available
- Consider using app-specific passwords if your provider supports them
- WarmySender encrypts stored credentials
- Credentials are never logged or exposed
Custom Domain Warmup
For businesses using their own domains (you@yourcompany.com), SMTP/IMAP integration is often the best choice. It works regardless of where your email is hosted and gives you full control over the connection configuration.
Connection Troubleshooting
If you have trouble connecting:
- Verify server addresses and ports with your provider
- Check that your password is correct (try logging in via webmail)
- Ensure your provider allows SMTP/IMAP access (some require enabling it)
- Try alternative ports if one is blocked
- Check for IP-based restrictions on your mail server

Frequently Asked Questions
What information do I need to connect via SMTP?
You need your SMTP server address, port, username (usually your email), and password. Your email provider's help documentation will have these details.
Is SMTP/IMAP as secure as OAuth?
SMTP/IMAP with TLS/SSL encryption is secure for most use cases. OAuth is preferred when available because it doesn't require sharing your password, but SMTP/IMAP is perfectly acceptable for email warmup.
Can I connect email from my web hosting?
Yes. Most web hosting providers (GoDaddy, Bluehost, HostGator, etc.) support SMTP/IMAP connections. Check your hosting control panel for email settings.
Why won't my SMTP connection work?
Common issues include incorrect server/port, wrong credentials, or SMTP access not enabled on your account. Try verifying each setting with your provider.
