Free email QA tool

Check every link before your campaign goes out.

Paste your email HTML and GMass will find every link, verify the destination, load the page title, and show you a screenshot. It works with HTML from any email platform.

1Paste your email

Drop in the HTML you’re about to send.

We’ll render it exactly as an email preview, pull out the absolute links, and inspect each destination.

How the link checker works
The checker analyzes the URLs in your HTML. Nothing here sends your campaign or changes its content.

Link checking is built into GMass too.

If you send with GMass, you don’t need to copy and paste anything here. Run the link checker from the campaign settings and inspect your links before you send.

Catch bad destinations before your recipients do.

A typo, expired page, or broken redirect can turn a good campaign into a dead end. Check the final destinations before launch.

Use it with any email service.

This standalone checker isn’t limited to GMass campaigns. Paste HTML from any email marketing platform and audit the links here.
