Where OpenMail and AgentMail differ
Less than half the price on paid plans
AgentMail's first paid tier starts at $20/month. OpenMail's Developer plan is $9/month — the same 10 inboxes and 10,000 emails, with double the storage at 20GB vs 10GB. For indie developers and small teams, that difference adds up.
Custom domain included on the free tier
AgentMail's free plan uses agentmail.to addresses. Your agents send from agent@agentmail.to until you pay $20/month. OpenMail includes one custom domain on the free plan — your agents send from your domain from day one, at no cost.
EU-based by default, not by upgrade
OpenMail is built and operated in Vilnius, Lithuania. Every customer on every plan is covered by GDPR — not as a checkbox, but as a legal guarantee. AgentMail offers EU cloud hosting as an enterprise-only option at custom pricing. If you're building for European users or handling EU personal data, that's a meaningful difference.
Where AgentMail has the edge
AgentMail is SOC 2 Type II certified and has official SDKs for Python, TypeScript, and Go. They've raised $6M and have a larger team. If SOC 2 compliance is a hard requirement for your organization, AgentMail currently has the edge there. OpenMail is the better fit for developers who want lower cost, EU data residency, and a custom domain without paying first.
