- Include a clear unsubscribe option in marketing emails
- Maintain a healthy text-to-link ratio (avoid too many links)
- Personalize your emails - generic content gets filtered

Frequently asked questions
What triggers spam filters?
Salesy phrases, all-caps, too many links, image-only bodies, missing unsubscribe links and mismatched sender domains.
Does this check my domain setup?
No. It checks the content. SPF, DKIM and DMARC are set at your domain; the cold-email deliverability guide on the blog walks through those.
Is my email stored?
No. The check runs in your browser.
