Mail.tm and Temp Mail both give you temporary email addresses without signup. But they serve different needs: Mail.tm is built for developers with an API-first approach, while Temp Mail is built for everyday users who want a simple, fast, mobile-friendly inbox.
Here is a direct comparison.
Quick verdict
Use Temp Mail if you want instant delivery, attachments, mobile-first design, fifteen languages, and an inbox you control. Use Mail.tm if you are a developer who needs a REST API for temporary email and you do not mind a more technical setup.

Who each service is for
Temp Mail is for everyday users
If you are signing up for a free trial, a verification code, a shopping discount, or a newsletter you will read once, Temp Mail is built for you. The interface is clean, works on a phone, and handles attachments in the browser.
Mail.tm is for developers
Mail.tm offers a REST API that lets you programmatically create temporary email addresses and fetch messages. This is useful for testing sign-up flows, automated testing, and integration projects. But for a human just trying to verify an account, the API adds unnecessary complexity.
Delivery speed
Temp Mail is optimized for instant delivery. Verification codes typically arrive within seconds. Mail.tm can also be fast, but delivery depends on API response times and server load.
Domain blocking
Major platforms maintain lists of known disposable domains. Temp Mail rotates domains regularly to stay ahead of blocks. Mail.tm uses fewer domains, so it is more likely to be blocked by services like Google, Facebook, and Twitter.
Attachments
Both services support attachments. Temp Mail renders them inline in the browser with clear download links. Mail.tm supports attachments through its API, which is useful for developers but less convenient for everyday users.
Languages
Temp Mail is available in fifteen languages: English, Arabic, German, Spanish, French, Hindi, Hungarian, Indonesian, Italian, Norwegian, Polish, Portuguese, Russian, Turkish, and Vietnamese. Mail.tm is English only.
Which should you choose?
Choose Temp Mail if you want a simple, fast, disposable inbox for everyday use. Choose Mail.tm if you are building software that needs temporary email addresses programmatically.
