Temp Mail / TempMail.is

Provides free disposable email inboxes for receiving signup, OTP, and app testing messages without registration.

1. TempMail.is is a free temporary email service that generates disposable inboxes in the browser. It is designed for receiving verification codes, OTPs, newsletters, signup confirmations, and test emails without using a personal inbox.

The homepage states that users can open the site and get a unique temporary email address instantly, with no signup and no captcha wall. Users can copy the address, create a custom username, choose a domain, switch inboxes, or delete an address when finished.

For developers and QA teams, the site positions TempMail.is as a lightweight email testing tool for registration, invite, password reset, OTP, and magic-link flows. It says developers can create unlimited disposable addresses and capture HTML or plain-text messages.

The privacy policy says the service processes temporary addresses and messages so the product can work, may keep some state in browser storage, and uses technical logs for operation and protection. It also warns that disposable addresses are not private like personal accounts.
