I Built a Disposable Email API for Developers

I Built a Disposable Email API for Developers

As a developer, I constantly run into the same problem while testing apps:

I need email addresses for verification emails.

Whether it's:

testing signup flows

password reset emails

QA automation

bot testing

CI pipelines

Using my personal inbox quickly becomes messy with dozens of test emails.

So I built OpenInbox — a disposable email service designed for both developers and regular users.

Why I Built It

Many temporary email websites already exist, but they usually have a few problems:

slow email delivery

overloaded with intrusive ads

no developer APIs

unreliable inboxes

I wanted something that was:

fast

simple

API-friendly

So OpenInbox was born.

What OpenInbox Does

OpenInbox lets you instantly create temporary inboxes and receive emails without signing up.

You can use it directly from the browser or through the API.

Common use cases include:

testing signup verification emails

automation scripts

QA testing

protecting your real email from spam

temporary registrations

Looking for Feedback

I’m continuously improving OpenInbox and adding new features like:

browser extensions

more API capabilities

automation tools

If you're a developer who needs disposable emails for testing, feel free to try it.
