Show HN: Mail42 – Disposable emails with AI-based text extraction

Hi HN,

I built Mail42 (https://mail42.ai) to make it easier to test email flows without dealing with regex or messy parsing.

The pain point: whenever I tested signup or checkout flows, I had to create throwaway inboxes and then write hacky regex just to grab a 6-digit OTP or a verification link.

With Mail42 you can:

- Generate disposable email addresses instantly for QA

- Query emails using natural language like "get the OTP" or "find the verification link"

- Use a simple REST API that works with curl, Postman, or your test suite

Example:

`curl "https://get.mail42.ai/?email=test.123@mail42.ai&prompt=get otp"`

Response:

847291

It’s lightweight and intended for testing env

I’d love your feedback:

- would you use this in your testing workflow?

- what features or integrations would make it more useful?

- are there cases where regex still feels more reliable?

Thanks for checking it out.
