Privacy Policy

Short version: every tool on this site runs entirely in your browser. Subject lines, preheaders and any other text you paste into the tester, generator, checker or previews never leave your device — there is no server that receives them, and nothing is stored.

What we collect

The site itself collects no accounts, no forms and no names. Like most websites, standard, anonymous analytics measure page views and tool usage events (for example, that a tool was used and succeeded — never what you typed). Advertising partners may set cookies to fund the free tools; you can opt out via your browser settings or industry opt-out pages.

Advertising

This site is supported by advertising. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits. You can opt out of personalized advertising via Google's Ads Settings. Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this and other sites.
