TrashEmail

TrashEmail is a small, open-source disposable-email project built and maintained by a single developer, and that's both its main selling point and its main limitation. The bot lets you spin up and manage up to eight temporary addresses at once, authenticated purely through your Telegram account — no password to create or leak. Incoming mail arrives as regular chat messages.

What sets it apart from the commercial bots in this list is transparency: the entire source is published on GitHub under an Apache license, so anyone technical enough can read exactly what the service does with the mail that passes through it, rather than taking a company's privacy claims on faith. The maintainer explicitly frames it as a non-commercial project with no ad revenue and no interest in mining user data.

The flip side is that it's a solo, community-hosted project rather than a company with paying customers and uptime obligations — reliability and long-term continuity depend on one person's time, which is a real trade-off compared to the established brands here. For a low-stakes throwaway address where you specifically care about not trusting a black box, it's a solid, unusually transparent pick; for guaranteed uptime, lean on a bigger name instead.
