My DMARC reporting said my SPF & DKIM had passed but hotmail and yahoo mail users dumped my emails into the junk folder.
DMARK was P=None for 3-4 months and DMARC checker returned a fail . Then changed p=reject and everything passed.

I'm wondering if I understand DMARC. If I set p=none for 30 days as you recommend, wouldn't that permit hackers to send email using my address during that time? Such emails would fail SPF but DMARC p=none would tell other email servers to accept the bogus emails anyway. No?

Thank you for this video. I don’t understand techy things. I jus recently started noticing all AOL and YAHOO clients emails were not delivered. Started getting non deliverable messages usually 24 hours after sending. I don’t send thousands of emails. Just a few a day. Trying to figure this out.

Great video. Thank you! Quick question - if I have been using an inbox warmup software for about 100 days now, and it passes all of the tests (DMARC, SPF, DKIM), am I ready to set the DMARC policy to "reject"? It's currently set to none, but I haven't started sending emails from this address yet outside of the warmup software.

I have set up the SPF, DKIM and DMARC correctly after hours of researching and try and errors. We're in 2024, why does it has to be so complicated.
