The MailerSend integration lets your agents send emails at the end of a call or on specific events.

​
Prerequisites

  1. MailerSend account - See getting started if needed.
  2. Verified domain - You must verify and authenticate a sending domain in MailerSend so emails deliver correctly and aren’t marked as spam. Follow How to Verify and Authenticate a Sending Domain.
Without a verified domain you cannot send from MailerSend. Complete this step before continuing.
