About Us

Cold Email Checker is a free tool built to help marketers, sales teams, and founders improve their cold email deliverability.

We know that getting emails into the inbox — not the spam folder — is one of the biggest challenges in outbound outreach. That's why we built a simple, fast, and privacy-respecting spam checker that analyzes your email content in real time.

How It Works

Our tool scans your email subject line and body for known spam trigger words and patterns. Everything is processed in your browser — we never see or store your email content.

Our Mission

We believe cold email can be done ethically and effectively. Our mission is to give everyone access to the tools they need to write professional, deliverable emails — without paying for expensive platforms.

100% Free, No Sign-Up
