A broken link is easy to miss in the editor and hard to take back once an email is sent.

Today, we're introducing a **link checker** in the [Broadcast](/features/broadcasts) and [Template](/features/templates) editors so you can catch issues before you send.

When you send a Broadcast or publish a Template, Resend checks the links in your email and flags:

- **Broken links** that return a 404 or other error
- **Missing or invalid URLs**, like empty buttons
- **Placeholder links**, such as `example.com` or TODO destinations
- **Anchor links** (`#...`), which don't work in most email clients

Click any issue to jump to it in the editor and fix it before you send.
