Postmark has a free tool to set up and monitor DMARC, which is another policy setting that can be used (if you own your domain) so that major email providers know whether or not to trust an email claiming to be from you. Postmark's tool lets you get digests and nice visuals of these automated ISP reports rather than you figuring out how to parse the XML they'd normally send directly to you. Disclosure: I'm not at all affiliated with Postmark, I use their free tier transactional emails, and I use their DMARC tool. https://dmarc.postmarkapp.com https://dmarc.postmarkapp.com
