Adding an Email Account

MailCopilot supports any email provider that uses standard IMAP and SMTP protocols. You can also sign in with Google using OAuth for a seamless experience.

Adding via the Setup Wizard​

When you click Connect email (the mail icon at the bottom of the sidebar) or open the account manager, you will see the setup wizard.

Step 1: Choose a Sign-in Method​

You have two options:

  • Sign in with Google -- opens a browser window where you authorize MailCopilot to access your Gmail account. No password entry is needed.
  • IMAP/SMTP account -- for any email provider (Outlook, Yahoo, Fastmail, your company mail, self-hosted servers, and so on).

Step 2: Enter Your Credentials (IMAP/SMTP)​

If you chose the IMAP/SMTP option:

  1. Enter your email address and password.
  2. Optionally enter a display name (the name shown in outgoing messages).
  3. Optionally enter an email address (From) -- this is the address used in the "From" field of outgoing messages. If left blank, the SMTP login address is used.
  4. If your SMTP credentials are different from your IMAP credentials, check "SMTP login/password is different" and enter them separately.
  5. Click Next.

Step 3: Server Detection​

MailCopilot will attempt to automatically detect your mail server settings using standard autodiscovery protocols. If successful, the detected IMAP and SMTP servers will be displayed.

  • Click Connect to test the connection and save the account.
  • If you want to adjust the settings, click Manual setup.

Manual Configuration​

If automatic detection did not find your server, or if you need to customize the settings:

  • IMAP: enter the host, port (typically 993), and check SSL/TLS.
  • SMTP: enter the host, port (typically 465 or 587), and check SSL/TLS.
  • Use the Autoconfigure button to try automatic detection again.
  • Use the Test connection button to verify your settings before saving.

Google Account (OAuth)​

Click Sign in with Google in the wizard. A browser window will open where you can authorize MailCopilot. Once authorized, the account is added automatically with the correct IMAP and SMTP settings.

TLS Certificate Verification​

MailCopilot always verifies TLS certificates when connecting to mail servers. If your server uses a custom or self-signed certificate, a trust prompt will appear during the connection test. You can review the certificate details and choose to trust it.

Managing Multiple Accounts​

You can add as many accounts as you need. To switch between accounts, use the sidebar or go to Settings > Accounts. The active account is highlighted, and you can set any account as the current one.
