Hi @kenmckown,
It looks like the issue might be related to the From Address you're using in the email.
I ran a few test cases to troubleshoot:
Case 1: Used my valid email address as the sender — Email was received successfully.
Case 2: Used a non-standard address (047ed-2ac@xyz.com) — Email was not received.
Case 3: Switched back to my valid email — Email was received again.
Based on this, I recommend using a valid and verified sender email (like your own) when testing, to ensure delivery.
Hi @kenmckown
As mentioned by @PeeyushSachdeva the from address in the email should be set to a legitimate email id.
By default in new email editor, from & reply to are set to a dummy @adobe.com id.
You can change this permanently from Admin>Email, so your subsequent mail will automatically take to default from email & you will not face similar issues again.
Hope this Helps 😊
