unMTA Is For
You're in the right place if any of these sound familiar.

You're sending serious volume on a traditional ESP like SendGrid and the bills are getting ugly.

Power Users
You've outgrown the rigid knobs of a hosted ESP and need fine-grained control, customizability, and visibility.

You operate under HIPAA, SOC2, GDPR, or data-residency rules and need email infrastructure that meets the same bar as the rest of your stack.
Multi-Tenant Platforms
You run a SaaS platform or agency that sends on behalf of your customers and need predictable costs at any scale.
Where unMTA Fits
At serious sending volume, every other option forces a trade-off.
Transparent Pricing
No per-message fees. No surprises. Just dedicated infrastructure at a flat rate. 30-day money back guarantee.
