AI newsletter proofreader: a score, clear fixes and better openings

Want a second pair of eyes before you hit send? Paste your issue and AI grades it on five points, quotes the lines worth changing and shows how to fix each one. You also get two subject line ideas and a stronger opening. Numbers, dates and product names stay exactly as you wrote them, and no new facts are added.

What you enter is sent to our AI provider (Anthropic) to create the result. We don't save it; only a short excerpt appears in an internal usage notice to our team.

How to use it

  1. Paste the text of the issue you plan to send. Add the subject line if you have one.
  2. Optionally describe your readers or business so the feedback fits them.
  3. Click “Generate with AI” to get a score, an overall note, the fixes, two subject lines and a new opening.
  4. Copy what you like, edit your issue and paste it again to compare the score.

The five things it scores (20 points each)

  • Subject: is it clear and specific enough to open?
  • Opening: do the first two or three sentences tell readers why this matters to them, without a long warm-up?
  • Readability: short paragraphs, plain words, easy to read on a phone.
  • Value: is there something useful or interesting, not just a pitch?
  • Call to action: is there one clear next step, rather than several competing asks?

Common fixes

  • A subject like “November newsletter”: put your most interesting point in the subject instead.
  • A long intro: one friendly line is enough. Get to the point.
  • Too many asks: “read this, sign up, follow us, reply” means readers do none of them.
  • No unsubscribe link or postal address: check your footer with the free email footer checker.

If writing every issue is the hard part

This tool helps you polish an issue you wrote yourself. If finding time to write is the real problem, Newsletter Ready drafts your next issue from your website, blog and new products, and you just read and approve it. Your text is sent to AI (Anthropic’s Claude) to generate the feedback and is not stored.

FAQ

Is it free?

Yes. No sign-up needed. You can use it up to 10 times an hour.

Should I hold off sending if the score is low?

No. The score shows what to fix first. Fixing the top finding is usually enough.

Will it change my facts?

No. Rewrites keep your numbers, dates and product names, and never add discounts or deadlines you didn’t mention. You decide what to use.
