Most of us have more than one email address: a work account, an old Gmail, a personal iCloud address, or a mailbox at a web host. Connected accounts let you add those other mailboxes to TrekMail so you can read, reply, and send from one inbox instead of opening several apps.
What a connected account does
When you connect an account, TrekMail talks to that provider on your behalf. Its messages appear alongside your own mail. Replies normally go out through that account and use its address. Your email stays at the original provider: connecting gives you another way to use the mailbox; it does not move or delete anything.
If you want to permanently copy old mail into a TrekMail mailbox, use email migration instead. Connect an account you plan to keep using; migrate an account you are leaving behind.
When Gmail receives mail for a business address
Some people publish an address such as brian@yourcompany.com but forward its mail into yourname@gmail.com. You can keep that arrangement. Under Settings → Sending addresses, link the approved business address to the connected Gmail inbox. Replies can then show the business address rather than the Gmail address.
The screen keeps three jobs separate: where mail arrives, what address the recipient sees, and which service sends the reply. See Send From a Business Address Using Gmail for an example.
Before you start
- Connect the account from the personal mailbox you use to sign in. Connected accounts cannot be added to a shared mailbox.
- Have access to the external mailbox and its security settings. TrekMail tests both receiving and sending before saving a new connection.
Providers you can connect
Almost any email service that offers IMAP works. The common options have setup guides:
- Gmail: use a Google app password when Google makes one available for the account.
- Yahoo and AOL: use a provider-issued app password.
- iCloud: use an Apple app-specific password.
- Outlook.com and Microsoft 365: sign in with Microsoft rather than entering a password.
- Any other IMAP mailbox: use the incoming and outgoing settings from the host or mail administrator.
Outlook.com, Hotmail, and Microsoft 365 use a Sign in with Microsoft step, so TrekMail never sees your Microsoft password. You can revoke access in your Microsoft account at any time. Microsoft sign-in is not offered on a branded White Label host.
App passwords
Gmail, Yahoo, AOL, and iCloud use a separate app password for this kind of connection instead of your normal sign-in password. It can be revoked separately in the provider's security settings. The provider decides whether app passwords are available; a work account, an advanced security program, or a provider policy can hide the option. Mailboxes at a regular web host usually use their normal mailbox password.
Connect an account
- In TrekMail webmail, click your profile picture, then select Settings.
- Choose Connected accounts and select Connect an account.
- Enter the email address. TrekMail recognizes common providers and fills in their server settings.
- Enter the password or app password, select Test connection, and save once the test passes.
The account appears in the sidebar under Connected accounts. Open it to browse that mailbox, or turn on All inboxes to see your mail and every connected account in one date-sorted list.
Connecting an inbox makes its own address available in From automatically. If it also receives forwarded mail for one of your business addresses, add that business address under Settings → Sending addresses.
How many can I add?
Starter includes 5 connected accounts per mailbox, Pro includes 10, and Agency includes 30. Nano does not include connected accounts. The Connected accounts screen shows current usage. Removing an account frees a slot and only disconnects it from TrekMail; it never changes mail at the original provider.
If something looks off
If an account has an amber dot or asks you to reconnect, its password may have expired or been revoked. See Fixing connected account problems for the common fixes. If you still need help, open a support ticket.
