How do I connect a mailbox for Autopilot?

Outreach Autopilot and Sending Hours · Updated September 22, 2026

In Settings, go to the Outreach Autopilot card, click + Connect A Mailbox, fill in your mailbox's sending details and click Connect And Verify. Legiit Leads signs in to your mail server there and then, and only saves the mailbox if that works, after which it shows a green CONNECTED badge. You can connect a mailbox on any plan; having Autopilot send from it needs Agency Pro or Agency Empire.

The mailbox form: from name, from email, SMTP details and the daily cap.

Steps

  1. Click Settings in the sidebar and scroll to the Outreach Autopilot card.
  2. Click + Connect A Mailbox.
  3. Fill in the fields (each one is explained below).
  4. Click Connect And Verify. The button reads Testing Connection… while it checks.
  5. When the check passes, the form closes and your address appears at the top of the card with CONNECTED and a count such as 0/30 sent today.

If the form shows a red message starting Could not connect: instead, see Why does Connect And Verify say Could not connect?

The fields

  • From name: the name prospects see, for example Casey at Reeve Digital. If you leave it blank, your email address is used.
  • From email: the address your emails come from.
  • SMTP host: your provider's outgoing mail server, for example smtp.gmail.com for Gmail and Google Workspace.
  • Port: 587 is filled in for you. See the ports below.
  • SMTP username: usually your full email address.
  • SMTP password (app password for Gmail/Outlook): for Gmail and Outlook, create an app password in your email account's security settings and paste it here, not the password you sign in with.
  • Daily cap for this mailbox: the most emails Autopilot sends from this mailbox in a day. 30 is filled in. Pick a number from 5 to 100; anything above 100 is saved as 100.

Which port to use

The Port field accepts 25, 465, 587 and 2525.

  • 587 is the one to use for Gmail, Google Workspace and Outlook.
  • 465 is for providers that ask for SSL.
  • 2525 is the usual alternative port for email relay services.

On 25, 587 and 2525 the connection switches to encryption when your mail server offers it. On 465 it is encrypted from the start.

Good to know

  • The check only signs in. It does not send a test email.
  • Your password is stored encrypted and is never shown again in the app. To change a mailbox's password or cap, click Remove on it and connect it again.
  • You can connect up to 10 mailboxes. Autopilot sends from the one with the most room left under its cap that day. See What is a mailbox's daily cap, and which mailbox does Autopilot send from?
  • Connecting a mailbox does not send anything by itself. Autopilot starts only when you tick Auto-Send. See How do I turn on Auto-Send?
