Take Control of Your Email Sending With PowerMTA
PowerMTA offers more reliable, scalable, and flexible sending than any other MTA. PowerMTA is an enterprise-grade email message transfer agent (MTA) for sending high-volume, business-critical email.
Why do serious email senders choose PowerMTA over open source MTAs like Postfix and competitors like Green Arrow, MailerQ, and SocketLabs?
We’ve been using PowerMTA in the public cloud (AWS) for 2 years and are impressed with how easy it is to deploy and manage. Our transition to the cloud was largely painless and PowerMTA functioned wonderfully in the new environment. It’s a modern and professional MTA that’s built for handling whatever we can throw at it with zero unexpected downtime.
