## What Jamie wrote

If you host your own email, and use it for things beyond just personal email, it is critical that you configure everything just right for deliverability. Since I send the Weekly Thing from thingelstad.com, I need to keep an eye on things and I've used the free version of [Postmark's DMARC Monitoring](https://dmarc.postmarkapp.com) for a long time. Cloudflare's new offering to do the same is impressive, and brings more data and trends. The writeup on [how they built it](https://blog.cloudflare.com/how-we-built-dmarc-management/) is interesting too.
