What is uchecker?
uchecker is an email verification service with a set of free email DNS tools attached.
The paid side takes a .txt or .csv list of up to 9 million addresses per job and returns Good, Bad and Risk lists in one archive, or JSON over the API, at about 3200 addresses a minute. Dead domains are removed automatically and for free, so there is no pre-cleaning step. For every address it keeps the mail server's full reply, so a deleted mailbox reads differently from a frozen account or a full inbox, and anything unresolvable goes to a separate Unknown group instead of being counted as valid.
Access is through a web dashboard, a REST API or a Telegram bot, with an MCP endpoint for AI agents.
The free side is 13 tools for email DNS records, none of which need an account: SPF, DKIM and DMARC checkers, MX lookup, an SPF record validator, an email domain health check, and generators for SPF, DKIM, DMARC, BIMI, MTA-STS and TLS-RPT.
