Temp Mail

Temp Mail is the Telegram bot built by temp-mail.io, one of the longer-running disposable-inbox services on the web, with apps for iOS, Android and browser extensions alongside the bot. Tap Start and the bot immediately hands you a random address; every message that arrives at it is forwarded straight into your chat with Telegram, no need to open a separate inbox or refresh a page.

The free address is valid for ten minutes, which is plenty for the classic use case — confirming a sign-up, downloading a whitepaper, unlocking a one-time coupon — without handing a real address to a site you don't trust. A paid subscription unlocks a custom domain, a full hour of validity and API access for people who want to script the whole thing.

Because the mailbox is genuinely disposable, don't use it for anything you need to recover later: password resets, banking, or any account where losing access to the inbox would be a problem. Treat it strictly as a one-way filter for throwaway sign-ups, and it does that job about as reliably as any bot in this category.
