App
We have made logging of failed emails more enhanced and visible.
In the email activity log, you'll now see why an email was dropped if you hover your mouse over the status - both for automated emails and emails sent through journeys.
The in-depth cause appears if the email was invalid, e.g., the email was listed as the receiver more than once (to/cc/bcc email is the same) or if the email size exceeded the maximum allowed.
The details of the email's status are shown in the email activity log as well as the activity log in the dialer - for easy access for agents.
