Guerrilla Mail and Temp Mail are two of the best-known disposable email services. Both let you receive mail without signup. But they differ in important ways: delivery speed, domain rotation, attachment support, and mobile usability.
This is a side-by-side comparison to help you pick the right one.
Quick verdict
Use Temp Mail if you want instant delivery, attachment downloads, rotating domains, and a mobile-first interface in fifteen languages. Use Guerrilla Mail if you need a simple address that lasts longer and you do not mind a slower, older interface.

Delivery speed
Temp Mail is built for instant delivery. Verification codes usually arrive within seconds. Guerrilla Mail can be slower, sometimes taking a minute or more for confirmation emails to show up.
If you are signing up for a service with a time-sensitive code, Temp Mail is the more reliable choice.
Domain blocking
Large services like Google, Facebook, and Twitter maintain lists of known disposable domains and block them. Temp Mail rotates domains regularly, which means if one domain gets blocked, another usually works. Guerrilla Mail uses fewer domains, so it is more likely to be blocked by major platforms.
Attachments
Both services can receive attachments. Temp Mail renders attachments in the browser and lets you download them. Guerrilla Mail also supports attachments, but the interface is less polished.
Mobile experience
Temp Mail is designed mobile-first. The interface works well on a phone, which matters because most verification codes arrive while you are on a mobile device. Guerrilla Mail works on mobile but feels like a desktop site squeezed into a small screen.
Languages
Temp Mail is available in fifteen languages: English, Arabic, German, Spanish, French, Hindi, Hungarian, Indonesian, Italian, Norwegian, Polish, Portuguese, Russian, Turkish, and Vietnamese. Guerrilla Mail is English only.
