Email Checker Pro

Email Checker Pro — The Complete Email Validation Suite
Delivering accurate, privacy-friendly email validation has never been easier. Email Checker Pro is a production-grade email validation platform that helps businesses, marketers, and developers clean their lists, protect their sender reputation, and improve deliverability — all from a single, beautifully designed app that runs on the web and your mobile device.

Built on a modern stack (FastAPI + Supabase + Redis + Flutter), Email Checker Pro combines the power of DNS-based validation with a slick, responsive interface. Best of all, it is completely non-intrusive: it never sends emails, never performs SMTP handshakes, and never probes mailboxes.

Core Validation Engine
Every email is run through a multi-step validation pipeline that returns a clear verdict and detailed reasoning:

Syntax verification — Instant detection of malformed addresses.
Domain registration check — Confirms the domain actually exists on the internet (DNS records present).

MX record validation — Verifies the domain is configured to accept mail, a strong signal of a real inbox.

Disposable / throwaway detection — Flags temporary and burner domains so you can keep your list clean.

Spam-risk classification — Each address is labeled as Valid, Risky (Disposable), Invalid syntax, Domain not registered, or No MX record, so you always know exactly what you're looking at.

Single & Bulk Validation

Single email check — Validate one address in an instant, with a detailed step-by-step breakdown of every check performed.

Bulk email validation — Clean up to 5,000 emails per batch asynchronously, with live progress tracking and downloadable CSV results.

File upload — Upload CSV, TXT, or XLSX files for server-side validation (up to 5 MB), then download the enriched results with a single click.

Domain Intelligence

Domain validation — Validate individual domains or batch-check up to 500 domains at once.

Smart typo suggestions — Let the app catch common mistakes and suggest corrections such as gmial.com → gmail.com
