Prompt

Turn the material below into one issue of my newsletter, {{newsletter_name}}. Readers: {{readers}}. Usual length: {{length}}.

Material (a thread, notes, or both; may be out of order and repetitive):
{{material}}

Do this:

1. Find the single most useful idea in the material and build the issue around it. Anything that doesn't serve that idea goes in a "Cut" list at the end instead of being forced in.

1. Write: a subject line (under 50 characters), preview text (under 90), an opening that starts with a specific moment or fact from the material, 2-4 short sections with plain subheads, and a closing that gives the reader one thing to try or to reply with.

1. Keep my voice: reuse my own phrasing where it's good, and don't add opinions I didn't express.

1. Where the material contradicts itself or a claim needs checking, flag it in [brackets] instead of smoothing it over.

Fill in

{{newsletter_name}}: Your newsletter's namee.g. The Small Shop Letter

Example input

newsletter_name: The Small Shop Letter
readers: owners of 1-5 person online stores
length: 250-300 words
material:
thread I posted tues (we sell refill cleaning concentrates):
1/ we killed free shipping in july. everyone said we'd die. we didn't.
2/ AOV went from $38 to $47 bc we added free shipping over $60 instead
3/ conversion dipped ~0.4 pts first 2 wks then came back mostly (2.9% → 2.5% → 2.8%)
4/ biggest thing: we were losing ~$6.10/order on shipping on small orders. that's gone
5/ customers complained way less than expected. 11 emails total. replied to every one w/ a 10% code
notes:
- message it on product page not only at checkout. surprise at checkout = abandon
- shopify shipping settings, flat $5.95 under $60
- someone replied to the thread saying their conversion tanked 30% doing the same thing. apparel? different margin
- margin up roughly 4 pts overall? need to check w/ accountant
- 'restock kit' bundle to push people over $60, worked, 18% of orders now include it
- the 10% code thing maybe cost more than it saved? idk

Subject: We killed free shipping. Here's what happened
Preview: Order values went up $9, and we got 11 complaints. The part that made it work was on the product page.

In July we stopped offering free shipping on every order. Everyone said we'd die. We didn't.

What we changed
Orders under $60 now pay a flat $5.95. Orders over $60 still ship free. The reason was simple: on small orders we were losing about $6.10 each on shipping. That loss is gone.

What happened to the numbers
Average order value went from $38 to $47. Conversion dipped in the first two weeks, from 2.9% to 2.5%, then came back to 2.8%. Overall margin looks up by roughly 4 points [check with your accountant before this goes out].

We expected a flood of complaints and got 11 emails. We replied to every one with a 10% code [your notes wonder whether the codes cost more than they saved; worth checking before anyone copies this].

What made it work
Two things. First, we show the $60 threshold on product pages, not just at checkout. A surprise at checkout is where people abandon. Second, we built a "restock kit" bundle to help people get over $60. It's now in 18% of orders.

A fair warning
When I posted about this, someone replied that their conversion dropped 30% after the same change. [Your notes guess they sell apparel; confirm before saying so.] Whether this works depends on your margins and what you sell.

Try this
Before you change anything, work out what shipping costs you on your smallest orders. Hit reply and tell me the number. I'll share what I hear next issue.

Cut

• The Shopify settings detail (setup, not the story; could be a short how-to later).

• Anything more on the 10% codes until you know whether they paid off.

Why it works

"Find the single most useful idea" is the step that turns a pile of notes into an issue with a point, and the Cut list makes leaving things out feel safe instead of lossy. Starting the opening with a specific moment or fact avoids warm-up paragraphs. "Reuse my own phrasing" and "don't add opinions I didn't express" keep it sounding like you. The [bracket] flags matter most with notes like these, which contain unverified numbers and second thoughts; a model left alone will state them as fact.

When not to use it

If your notes have no clear takeaway, the model will pick one, and it may not be the one you'd choose; tell it the main point instead. It's not built for roundup or link-list newsletters. Always check any figure it carries over, especially the ones you marked as uncertain in your notes.
