As of July 26 2024 whenever a person is added to a campaign under affiliate manager there is an automated message that is sent, but it's defaulting to support_am@donotreply.leadconnectorhq.com as the sender email. This needs to default to the domain we set either in email services or allow it to be set inside of the affiliate manager area for the domain we control.
Here's the current error I'm seeing on an SMTP provider:
'The 'From' address you supplied (support_am@donotreply.leadconnectorhq.com) is not a Sender Signature on your account.
