About this launch

uChecker is built for a list you already exported. Feed it a .txt or .csv. One job can take up to 9 million addresses at about 3200 a minute. There is no pre-clean step. You get Good, Bad and Risk. Unknown stays out of the valid count. The full SMTP reply is kept. Work from app.uchecker.net, api.uchecker.net/docs, @uchecker_bot, or https://uchecker.net/mcp. Thirteen DNS tools stay free at https://uchecker.net/tools.
