MailYx is an enterprise-grade transactional email REST API built for scale and sub-50ms latency. Written in Go, it features a visual template editor, real-time webhooks, instant logs, and a generous free tier (3,000 emails/month) for indie hackers.
Hey Product Hunt! 👋 I'm the maker of MailYx.
As developers, we send a lot of transactional emails (receipts, password resets, welcome emails). But we kept running into the same issues with legacy providers: slow API response times, clunky dashboards, and restrictive pricing for early-stage projects.
So, we decided to build the email infrastructure we always wanted to use.
MailYx is built entirely in Go (Fiber) from the ground up to be absurdly fast. We consistently hit sub-50ms latency for API responses, meaning your app never hangs while waiting to dispatch an email.
We also built in the features developers actually care about:
⚡ Sub-50ms API response times
🎨 A beautiful, built-in visual template editor
🪝 Real-time webhooks for delivery events
🪵 Instant, searchable email logs
💸 A generous free tier (3,000 emails/mo) so you can build side projects without a credit card
I would absolutely love to hear your feedback on our API design, the dashboard UI, or our Go architecture! I’ll be hanging out in the comments all day to answer your questions.
