“Posthawk replaced three services I was juggling — sending, receiving, and scheduling behind one clean API. Cut my email code in half.”
Sarah Chen
Freelance Developer
“Migrated off SendGrid in a weekend. The API is simpler, and the overage pricing is noticeably cheaper than what I was paying.”
Marcus Rivera

“Inbound parsing is the part nobody else does well. My whole support-ticket flow runs on Posthawk webhooks now.”
Aisha Patel

“We self-host with one Docker command and keep every byte on our own infra. No lock-in, no per-email surprises.”
Jonas Eriksson
Developer at ZippyRows
“Same import in my Next.js routes and my Cloudflare Workers — fetch-based, zero Node polyfills. It just runs at the edge.”

“I wired the MCP server into Claude and now it sends my release emails on command. Didn’t expect email to be the fun part.”
