Hello,

What I could suggest is using the mail tester website which will give you a report on what could be wrong with your emails:

https://www.mail-tester.com/

Just send an email to the email address that you see on the site, and then check your score.

Another thing that I could suggest is using an SMTP service like SendGrid for example. They offer a free plan as well.

Regards,
Bobby
