Rapid Email Verifier

Use it when

• Signup or lead-capture forms are accepting mistyped, dead-domain, or disposable email addresses that later pollute your CRM and bounce during outreach
• You need to bulk-check a list of collected contact emails for validity, disposable providers, and role accounts without paying a commercial verification vendor or sending the data to one

What it solves

Not the fit when

• Confirming a specific mailbox actually exists or accepts mail - the README states SMTP-level existence verification is not reliably possible; use double opt-in instead
• Sending email, checking deliverability of your own sending domain, or fixing HTML email rendering
• email-render-break
• notification-delivery-gap

Install

No install needed for the hosted API. Self-host: docker pull umutert/emailvalidator:latest && docker run -p 8080:8080 umutert/emailvalidator:latest (or docker-compose up -d for the full stack with Redis)

Invoke

GET https://rapid-email-verifier.fly.dev/api/validate?email=user@example.com for a single address; POST /api/validate/batch with {"emails": ["a@x.com", "b@y.com"]} for up to 100 emails. Self-hosted service listens on http://localhost:8080 with the same endpoints.
