Building a developer first temporary email service
Anshu Sharma · 2026-04-24 · via DEV Community

Anshu Sharma

I built a disposable email API for developers

While working on multiple side projects, I kept hitting the same bottleneck:

Testing email flows is painful.

  • You don’t want to use your personal inbox
  • Test emails clutter everything
  • Most temp mail services are not API-friendly

So I built: 👉 Devmail

What it does

  • Generate disposable email addresses instantly
  • Receive emails in real-time
  • Access inbox programmatically via API

Why this matters

If you're building:

  • authentication systems
  • SaaS products
  • automation scripts

You need a reliable way to test:

  • OTP flows
  • verification emails
  • transactional messaging

Key features

  • No signup required
  • Lightweight API
  • Fast inbox refresh
  • Developer-first design

Example use case

You can integrate it into automated tests:

  • create temp email
  • trigger signup
  • fetch verification email
  • extract token
  • complete flow

Looking for feedback

I’m actively improving this and would love input:

  • missing endpoints?
  • performance issues?
  • feature requests?
