MailEngine.
Self-hosted email infrastructure that pushes 10M+ emails per hour from a single server, one command deploys a production-grade SMTP/IMAP gateway with IP rotation, analytics and a 9-engine spam filter.
MailEngine is battle-tested, self-hosted email infrastructure, enterprise-grade sending without the enterprise bill or the vendor lock-in.
The challenge.
Growing senders were trapped in per-email pricing and bloated cloud stacks, paying more the more they grew, with almost no control over their own deliverability or reputation.
What we built.
We built a single command that stands up a complete mail gateway in under ten minutes, SMTP relay, IMAP, DKIM, DMARC and SPF, multi-IP rotation, intelligent bounce processing, a 9-engine spam filter and real-time analytics, all production-hardened and multi-tenant isolated.
The result.
A single lightweight server now pushes 10M+ emails per hour at a 98%+ inbox rate, with zero per-message fees and no vendor lock-in, the same engine that powers our own SendJot platform.
