I have found that it is recommended to use different subdomains to differentiate the reputation of different types of emails (for example: marketing or transactional).
However, using AWS SES I realize that the EMAIL FROM and the from field are two different things.
I have set my EMAIL FROM to be @mail.mydomain.com. When it comes to reputation and deliverability, should I also split my from fields into subdomains, or is it enough to use subdomains for different EMAIL FROMs?
Or put another way. Do I run more risks if I send emails from contact@mydomain.com than contact@mail.mydomain.com even if the EMAIL FROM is already from a subdomain?
Thank you very much!
