inboxsink, the disposable inbox that extracts the code for you
A no-signup disposable email service that displays verification codes directly and offers an API for automated signup tests.
Field notes
The homepage separates casual use from automated testing: a visitor receives a temporary address, while test code calls createInbox and then waits for delivery through a dedicated wait route. The example fills a signup form, waits for the incoming message, and inserts the extracted OTP. The service states that inboxes receive only, block remote images, isolate HTML from scripts, and erase messages after one hour; API access is described as 1,000 calls per month on the free tier.
