Spammers are better at SPF, DKIM, and DMARC than everyone else

My biggest problem with SPF, DKIM, DMARC is when you go to test this crap there's really only commercial apps. So people who are setting up things for a non-profit or a personal project are either forced to pay after doing 3 or 4 test emails or you wait like 24 hours or some crap.

And all that just for the privilege of being able to send email to some gmail accounts. Trying to get email to properly encrypt is pulling teeth and yet I still get hundreds of thousands of spam a month on my gmail account.

Any time I have to set up an email server on a new system I just kind of die a little.

I built a free DMARC/DKIM/SPF checker: https://dmarcchecker.app/. No usage limits, no ads—just a small footer link to one of my other projects. Made it for the exact reason you mentioned.

This is awesome. Thanks! Sensible, easy to use, easy to understand the results.

I've been trying the google one, for example, and it doesn't even work. "request timed out." Fishy, because yours works great.

much appreciated!
