Guide

Your first Letterflow run, start to finish

If you want to know what a good first session looks like, it is this: one real newsletter in, several usable posts out.

Bring one finished issue, generate the batch, pick the strongest drafts, and leave with content you can actually publish.

Paste a real newsletter, not rough notes

Letterflow can only repurpose what is already there. Use a finished issue with a clear point, real examples, and phrasing you would actually publish. If the source is weak, the outputs will be weak.

  • Use the full issue so the model can see the full argument.
  • Start with the version you sent or were ready to send.
  • Keep the structure intact instead of trimming it down first.

Pick the winners fast

The first batch is about finding strong angles, not rescuing every draft. Keep the posts that already sound close to right, edit the obvious winners, and regenerate only when a platform needs a different angle.

  • Choose the best draft for each platform before you start editing.
  • Fix the hook, ending, and any awkward phrasing first.
  • Regenerate weak drafts instead of over-editing them.

Stop writing social posts from scratch

Letterflow turns one newsletter into a week of platform-ready content so your promotion starts with the writing you already trust.

End with something scheduled or published

Do not finish your first run with a pile of drafts you might revisit later. Finish with at least one post ready to go live so Letterflow becomes part of your workflow, not just another tool you tried.

  • Publish or schedule the strongest post while the issue is still fresh.
  • Save the best outputs because they become useful voice samples later.
  • Repeat the same flow every time a new issue is ready.
