Gmail is becoming a real pain
I have a working platform and already active customers. When they register, a transactional e-mail is sent (through Mailgun). An introductory text, their user and temporary password and a link to the sign_in page.
I have found out most of the time is reaching the promotion category and some others even SPAM.
The account is new, and no SPAM have been ever done.
I really don't know how to deal with that. Any ideas?
Hey Juanse, did you setup SPF, DKIM and DMARC records in your DNS?
If not check this guide https://postmarkapp.com/guides/dmarc
I have a lot of domains and for best deliverability I configured these records on all of them. I also track DMARC reports, to see if someone is trying to send on behalf of my domains.
