Substack Name Checker

Not quite. Your publication lives at yourname.substack.com, and your writer profile has its own @handle. This checker looks at the publication address, which is the one readers subscribe at.

If you can. Substack lets you point your own domain at your newsletter, so readers and search engines learn an address you own. Every search here checks the .com and other extensions.

Short, easy to say, and clear about the topic or about you. Avoid dates and numbers, and check the matching handle on X and Bluesky where you'll promote it.

Add a word like weekly, notes, letter or dispatch, or use your own name. Then check the new version everywhere at once.
