Overview
Best practice for most customers:
- Receive email using IMAP (sync across devices)
- Send email using SMTP2GO (better deliverability)
What you need
- Email address (name@yourdomain.com)
- Mailbox password (for IMAP)
- SMTP2GO server + credentials (for sending)
Incoming (IMAP) typical settings
- Username: full email address
- Password: mailbox password
- Port: 993
- Encryption: SSL/TLS
Outgoing (SMTP) via SMTP2GO typical settings
- Host: SMTP2GO server provided
- Port: 587 (STARTTLS) or 465 (SSL)
- Authentication: enabled
- Username/password: SMTP2GO credentials
Outlook (manual setup)
1) Add Account → IMAP
2) Enter IMAP server/port and credentials
3) Enter SMTP2GO server/port and credentials
4) Ensure “Outgoing server requires authentication” is enabled
5) Save and test
iPhone (Mail)
1) Settings → Mail → Accounts → Add Account → Other
2) Add Mail Account → choose IMAP
3) Enter incoming IMAP details
4) Enter outgoing SMTP2GO details
5) Save and send a test
Android (Gmail app)
1) Gmail → Settings → Add account → Other
2) Choose Personal (IMAP)
3) Enter IMAP settings
4) Enter SMTP2GO settings
Troubleshooting
- Can receive but cannot send: wrong SMTP2GO credentials, wrong port, or auth disabled
- Authentication failed: mixing mailbox password with SMTP2GO password
- Spam issues: missing SPF/DKIM/DMARC or sending from unauthorized server
Validation
Send an email to Gmail and check “Show original” for SPF/DKIM pass results.
