# TempMail.is — A Disposable Inbox for Indie Launch Day: Test every signup flow without touching your real inbox

> Launch day is the worst time to discover a broken signup. TempMail.is gives makers and testers a throwaway inbox that works the instant the page loads — no signup, no install, no settings. Paste the address into a trial, a beta form, or a waitlist, confirm like a normal user, and watch the verification code land. When the test is over, delete the address and the follow-up drip emails go with it. Run the same flow ten times with ten fresh addresses and your real inbox stays empty through all of them. The honest limit: it is a temporary, receive-only inbox. Perfect for testing signups, trials, and downloads — not for banking or anything you need to keep.
