Mailnesty is a disposable, temporary email service that anyone can use instantly without signing up. Our goal is to help you handle the verifications you need online without exposing your real email address, protecting you from spam and data leaks.
Almost every website today asks for email verification at sign-up. The trouble is that once you hand over your address, an unending stream of marketing mail, newsletters and leak-driven spam starts to pile up. Many people end up missing the messages that actually matter, buried under advertising.
Mailnesty breaks that cycle by offering a "use-once and discard" temporary address. The core idea is simple: keep your real inbox clean, and reach for a disposable address only in the moments you need a one-off verification.
An instantly issued random temporary address, a live inbox that shows incoming mail without a refresh, and automatic OTP extraction that finds verification codes in the message body so you can copy them in one tap.
You also get Favorites for saving addresses you reuse, multilingual support in Korean, English and Japanese, and a custom-address feature (with optional Google sign-in) that lets you choose your own address name. Every feature works in the browser alone — no app or extension required.
We handle only the minimum information needed to run the service. Temporary addresses and received mail are automatically and permanently deleted once their lifetime expires, and deleted data cannot be recovered. We do not track your real identity or build a profile of you.
You can find the full details of how we handle data in our Privacy Policy, which also covers our use of advertising and cookies.
Mailnesty never charges its users. The cost of running the service is covered by ads shown on the page, which is what lets anyone use temporary email without paying a thing.
