Picked up one code last time they were here and set it up later with a handful of domains right before Microsoft added their policies around DMARC records for sending to outlook email addresses.

DMARC Report really exceeded my expectations and I particularly like the hosted DMARC, MTA-STS etc. records.

It's like the convenience of Cloudflare for managing your DMARC and other email related DNS security records. Keeping them in a centralised hub for easy updating while being able to see reports.

I found some strange phenomenon with one of my domains sending way above what it should be. Once I switched from DMARC monitoring only to reject, that volume has since dropped off to around where it should be. So it appears there were hundreds of thousands of spoofed emails monthly from that domain. I don't know how much volume was being sent exactly, as that one domain used all of my T1 quota within a day or two haha.

Overall very happy with DMARC Report and glad to see they aren't locking LTD buyers out of new features like managed records. In light of this great track record and my pleasant experience with their tool, I've gone ahead and full stacked this time around. Looks like they are adding some great new features also, based on their updates in the Q&A.

I think some of the help/info baked into the UI could be improved, to help users understand what each setting does incl. their current settings - or at least improved linking to help resources. It seems to assume that you have a decent understanding of DMARC records.

Even if you don't email much, if you just have a website/domain - then DMARC should be used to prevent people spoofing your domain without your knowledge and damaging it's reputation.
