Where OpenMail and AgentMail differ

Less than half the price on paid plans

AgentMail's first paid tier starts at $20/month. OpenMail's Pro plan starts at $9/month — the same 10 inboxes and 10,000 emails included, then usage-based pricing as you grow instead of forcing an upgrade to a pricier tier. For indie developers and small teams, that difference adds up.

Custom domains at half the price

AgentMail's free plan uses agentmail.to addresses. Your agents send from agent@agentmail.to until you pay $20/month. OpenMail custom domains start on the Pro plan at $9/month — your agents send from your domain without paying AgentMail's full price.

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 custom domains from $9/month instead of $20/month.
