GoDaddy Professional Email works in any mail app that speaks IMAP. Incoming mail (IMAP): imap.secureserver.net, port 993 (SSL/TLS). Outgoing mail (SMTP): smtpout.secureserver.net, port 465 (SSL/TLS). The user name is your full email address, and the password is your mailbox password. In LocalInbox, choose Other IMAP account and type these in under Server settings.
These settings are for GoDaddy's Professional Email (powered by Titan). Microsoft 365 from GoDaddy works only with Microsoft's own sign-in, which this version of LocalInbox doesn't include yet.
Server settings
| Server | Host name | Port | Security |
|---|---|---|---|
| Incoming (IMAP) | imap.secureserver.net | 993 | SSL/TLS |
| Outgoing (SMTP) | smtpout.secureserver.net | 465 | SSL/TLS |
For Professional Email mailboxes on your own domain. GoDaddy says Microsoft 365 no longer supports IMAP settings in most mail apps.
What the ports and security mean: IMAP ports and SMTP ports.
Steps
- In LocalInbox, open Settings › Accounts and click Add Account (or use the welcome screen the first time).
- Choose Other IMAP account. Enter your GoDaddy address, and your mailbox password as the password.
- Open Server settings. Under Incoming mail (IMAP), enter imap.secureserver.net and port 993, and choose TLS.
- Under Outgoing mail (SMTP), enter smtpout.secureserver.net and port 465, and choose TLS.
- Leave User name empty, and LocalInbox signs in with your full address, which is what GoDaddy expects.
- Click Connect. LocalInbox signs in and starts syncing your mail.
Troubleshooting
LocalInbox says the password is wrong
LocalInbox needs your mailbox password. Copy it again, without spaces before or after.
LocalInbox says it can't connect
The message says what to fix: nothing answering at the port, the wrong kind of TLS for the port, an untrusted certificate, an unknown server name, or a timeout. Check what you typed under Server settings against the table at the top of this page.

GoDaddy Professional Email's settings were checked against its own help pages in November 2026 and can change. The steps in LocalInbox come from the app.
