An email channel can send and receive emails in several modes of configuration, such as Postmark, IMAP/SMTP, or a hybrid configuration. Your organization will choose a configuration mode based on your operational needs, technical constraints, and desired speed of implementation. Depending on your selection, you may need to configure different sections when you create an email channel.
If you want to connect a Google account to an Email channel, Google requires the use of passwords that have been generated by App passwords instead of by the Less secure apps setting, which was removed from the Google account configuration page. You should use the 16-character password generated when connecting your Gmail account to the Engage Digital email channel.
