Description
One line
SimpleVerifier checks whether an email address can receive mail, and publishes the data behind it.
Boilerplate
SimpleVerifier is an email and phone verification service. It checks whether an email address can receive mail: syntax, domain, disposable and role-address detection, and a live SMTP mailbox check where the provider allows one. A result that could not be confirmed is marked risky, never valid. It offers a web app, CSV bulk upload, an API and an MCP server for AI agents, free tools that need no sign-up, and original email data studies whose raw CSVs are free to reuse under CC BY 4.0.
