Valimail alternative: open source and self-hosted

Valimail is an enterprise-focused platform known for automated enforcement and strong compliance credentials. It offers a free self-service Monitor tier, with paid Enforce plans above it. DMARC Analyzer takes a different approach to the same problem: open source and self-hosted, unlimited domains at no cost, and report data that stays on infrastructure you control.

Where Valimail fits

If you’re a large enterprise that wants a fully managed, sales-supported enforcement service with formal compliance backing, that’s Valimail’s home turf.

Where DMARC Analyzer fits

If you want to self-host and keep report data on your own infrastructure, or you need unlimited domains without a per-domain cost, DMARC Analyzer gets you the same core DMARC visibility on your own terms. The trade is real, though: you run the server, you do the enforcement work yourself, and support is the issue tracker rather than an SLA. Follow the path from monitoring to enforcement at your own pace.

Worth being plain about the overlap: if a free hosted monitor is all you need and you’re comfortable with the data living in a vendor’s cloud, Valimail’s Monitor tier covers that without you running anything.
