If you want your emails not to get in spam you need a few more things than just a DMARC. Specially when you are sending mails to Windows or Google you need to have a good reputation. They got spam filters wich will add you to the spam folder quickly if you have a small problem with your reputation. Get some more information about the following protocols if you want to get a good repu:

  • SPF
  • DKIM
  • PTR

After you researched some more about these protocols and still have troubles don’t hesistate to ask me.
