Webmail Lookup

About Webmail Lookup

Webmail Lookup is a single-purpose developer API that solves a small, real conversion problem: after a signup or a magic-link request, the user is told to check their email and then has to go find it, which is where a measurable share of them quietly stop. Given an address, the API identifies the webmail provider behind it, so your 'check your email' screen can render a direct button into Gmail, Outlook, Yahoo or whichever inbox that address actually lives in, instead of a generic instruction. The same lookup does double duty on the trust side, flagging disposable and free email services so you can decide whether to gate a trial, require verification or let it through. Response time is advertised at three milliseconds average, which matters because this call sits directly in the signup path where any latency is visible; more than 538,000 requests have been processed. The pricing is refreshingly plain for an API of this size: an unlimited monthly subscription at a flat rate, or credit packs at one credit per request for teams whose volume does not justify a subscription, with 1,500 free credits on signup. The company behind it is a registered Scottish limited company with its address published on the homepage.
