Check out https://dmarcdigests.com/. The pricing is great, and their interface was good enough for when I implemented some stricter DMARC policies for a handful of domains. Definitely worth it for $10/month/domain. Source: about 2 years ago

I'm fighting with a 3rd party marketing company that continues to blame our setup for their content failing SPF alignment and DMARC compliance. We use dmarcdigests.com and on a weekly basis we get a report for our domains. Most are fine, except for one of our domains that sends a lot of communication out using this specific 3rd party (not a major player, I'll leave it at that). Source: about 2 years ago

Thanks, based on the results of dmarcanalyzer.com, some others and my own checking we should be a at 3 lookups, thus well below the limit of 10 lookups as specified in RFC7208. :-). Source: about 2 years ago

I can send to my own e-mail just fine. Running tests on dmarcanalyzer.com returns PASS for both SPF and DKIM. The mail header that I get back from Microsoft shows. Source: about 2 years ago
