About

UserCheck is an email validation API that checks addresses and domains for disposable mail providers, forwarding services, public email domains, role accounts, MX record validity, syntax errors, and common typos. It returns structured signals such as disposable, relay_domain, public_domain, role_account, mx, and did_you_mean so developers can block fake signups or prompt users for a different address.

The free plan includes 1,000 credits per month, 1 request per second, a limited request log, unlimited user seats, multiple API keys, and access to UserCheck Gates. It is aimed at small projects and evaluation use, with no credit card required for signup.

This free tier is a genuinely usable monthly plan rather than a short trial: it includes 1,000 credits that reset each month, plus unlimited seats, multiple API keys, and access to UserCheck Gates, and the page explicitly says no credit card is required. Because the cheapest paid plan is Pro but its price is not published, the free tier is best valued as a modest but real starter offering worth about $3/month, with the main limits being the 1,000-credit cap, 1 rps limit, and limited request history.
