With Google
Choose Google when adding a mailbox, then authorize access in your Google account. The app requests sending and the reading needed to track replies. Public Google connection is under review; some access remains limited to authorized testing.
With SMTP and IMAP
Use the settings supplied by your host: outgoing SMTP server, incoming IMAP server, ports and encryption. Your provider may require an app password. Checking a connection does not itself launch a campaign.
Multiple mailboxes in one campaign
Connect mailboxes in “Mailboxes and signatures”, then select those to use in the campaign. Each contact should keep the same sender for follow-ups. The daily cap remains specific to each mailbox.
Disconnected or expired authorization
Reconnect in the app if the provider withdraws access or credentials change. Do not dismiss a security warning without understanding its cause. To revoke Google access, use your Google account’s third-party connections.
