CheckEmailDelivery.com is a free, community-first tool that helps freelancers, startups, marketers, and developers diagnose why their emails land in spam — and shows them exactly how to fix it, in plain English.
Millions of emails silently die in spam folders every day. The sender never knows. They just wonder why nobody replies.
Existing deliverability tools either cost $30–$100/month, require complex setup, or give you raw data like SPF: PASS without explaining what it means or what to do about it.
We built CheckEmailDelivery.com to change that. One test. One report. Plain English. Every issue comes with a clear explanation of why it matters, how to fix it, and the impact on your delivery rate.
This tool is — and always will be — free for everyone. No subscription. No credit card. No signup wall. We believe email deliverability should be accessible to every person who sends an email, not just companies with big budgets.
We don't believe in paywalling email health checks. This tool is free — today, tomorrow, always. We sustain it through community support and future premium features for teams.
We never read your email content. All test data is automatically deleted within 1 hour. We don't track you, and we never sell data.
Technical reports are useless if you can't understand them. Every issue in our reports includes a human-readable explanation and a step-by-step fix.
We're building this in public, for the community. Your feedback shapes every feature. We're in this together — your support makes it sustainable.
We're in early stages, and we're transparent about it. Right now, we run on limited infrastructure which means we cap usage at 5 free tests per person per day.
As we grow — with your support and feedback — we'll expand capacity and add more features. Every piece of feedback you share helps us build the tool you actually need.
