Set up email on a phone or desktop client
Server settings for IMAP and SMTP, and why to prefer the official app when there is one.
Google Workspace and Microsoft 365 work best through their own apps, which handle sign-in, two-factor and calendars without manual settings. Use IMAP when you prefer a different client, and for Titan.
IMAP and SMTP settings
| Server | Port | Security | |
|---|---|---|---|
| IMAP (incoming) | imap.titan.email | 993 | SSL/TLS |
| SMTP (outgoing) | smtp.titan.email | 465 | SSL/TLS |
The username is always the full address, including the domain. Authentication is required for outgoing mail.
Common mistakes
- POP instead of IMAP. POP downloads and often deletes from the server, so the phone and the laptop see different mail. Use IMAP.
- Port 25 for sending. Blocked on most consumer networks. Use 465, or 587 with STARTTLS.
- Username without the domain.
