Spam Word Checker — free online tool
You write a careful email, hit Send, and it lands in someone's spam folder. Often it's a few words that set off the filters — and you have no easy way to spot them. We added a free tool that does it — Spam Word Checker — right in your browser.
What it does
Paste your email and it gives you an instant deliverability risk score. Every spam-trigger word is highlighted and grouped by category, so you can see at a glance what might be pulling your message down — before you hit Send.
Nothing leaves your device
The whole check runs in your browser. Your email text is never uploaded and never saved anywhere. When you close the tab, it's gone.
How to use it
- Open Spam Word Checker and paste your email into the box.
- Read your risk score and look at the highlighted words by category.
- Reword or remove the flagged words, then send your email with more confidence.
It's free with no limit. There are more small tools on the Apps page.
