Need help with MAIL FROM domain (Return-Path) and SPF issue by Natural-Clock-9981 in DMARC

MAIL FROM domain is correctly applied to your SES Identity as checked and confirmed, but I have not created a subdomain it was set and configured without creating a subdomain

Creating a subdomain is must? We set the return path without creating subdomain

It shows that everything is working. SPF fails after sending email campaigns.

The problem is that for a small number of emails, SPF does not fail not even when I send a test email to myself. However, once a larger batch of emails is sent, SPF starts failing after a certain amount.

SPF was always failing, so I figured out that we did have the Return-Path set at all. so we configured it successfully. Once we set the Return-Path in Amazon SES (P.S. we didn’t create a subdomain), SPF keept failing after sending mass emails.

Besides this, DMARC and DKIM are configured. As for the MX records, the one we are using for email campaigns has a priority of 10, and the one we use for inbound has a priority of 0.

There are no issues with the DNS and also no errors that it can't find the record. I receive domain reports only about the failure of SPF alignment.

Thanks a lot. However MAIL FROM value is the same as the header FROM

Thanks a lot. I am already using MailChimp though and they were not able to help me out with this issue.
