RE: Marketing email automatic response send to "From" user rather than "Reply To" user
Hello, Amey
Thank you for your question.
Automatic replies are designed that way, that it should go to the Return-path address, not Reply-to.
It is designed and written into RFC3834 standard for the whole email industry.
As per RFC3834 paragraph 4 says:
Where to send automatic responses (and where not to send them)?
In general, automatic responses SHOULD be sent to the Return-Path field if generated after delivery. If the response is generated prior to delivery, the response SHOULD be sent to the reverse-path from the SMTP MAIL FROM command, or (in a non-SMTP system) to the envelope return address which serves as the destination for non-delivery reports.
The Reply-To field SHOULD NOT be used as the destination for automatic responses from Personal or Group Responders. In general, this field is set by a human sender based on his/her anticipation of how human recipients will respond to the specific content of that message.
So in short, reply-to address is not used for automatic replies. This email header serves only for human replies - so that you may test and make a manual reply to that email - and it will go to reply-to address.
For more detailed information you may want to check full RFC3834 standard document. It is publicly available in the internet.
For your case I can suggest one of the following solutions:
1) You may set up custom filtering rule on your inbound mail server/your CEO mailbox that would be catching and redirecting all automatic replies sent to your CEO and forwarding them to the email address that you want to receive those emails.
2) Second way is somewhat more complicated. You may create a custom email address or email alias on your mail server, that would represent your CEO, but will not be connected directly to his actual email address. You may us this customer email address for sending you email campaigns. With that way you will have a dedicated email address that would collect all replies and autoreplies without sending them to your CEO email address.
Hope you will find this information helpful
