MESSAGE QUALITY
Help AI write a clear subject line.
Paste your email and give AI the facts it can use. Ask for a few subjects and preview lines. Check that each one matches what is inside.
In this guide
A prompt you can copy
A prompt is the task you give AI. Start with this one, then add your own store’s details.
Copy this prompt. Replace the tote with your item.
Write three subject-line and preview-text pairs for the email below. Keep the words plain and the sentences short.
Email: The shopper left an olive Everyday Tote in their cart. The email shows that tote and a button back to the saved cart. It says: “Your olive Everyday Tote is still in your cart. Take another look, or pick up where you left off.”
Facts: There is no discount, deadline or stock warning. The item is not reserved. We do not know why the shopper left. Do not add any of those claims.
Store voice: casual and direct. We would say “Back for that tote?” We would not say “Unlock your next adventure.”
Return three pairs: one plain reminder, one casual question and one that names the chosen color. Make each preview add a detail. Under each pair, say which fact from the email it uses. If a detail is missing, leave it out rather than guess.
Use your actual email and checked facts. Keep the “no discount” rule only when it is true. The examples in the guide are worked drafts, not measured winners.
1. Start with the email
Paste the email into your request. AI needs to know what is inside. Is it a sale, a care guide or a cart reminder?
Add the key facts. Here, they are an olive tote and an open cart. The button goes back to that cart. There is no deal, time limit or stock warning.
Show how your store talks. Try “Back for that tote?” as a line you would use. Add “Unlock your next adventure” as one you would avoid.
2. Check each claim
Take “Last chance! Your dream tote is almost gone.” “Last chance” adds a time limit. “Almost gone” adds low stock. “Dream tote” guesses how the shopper feels. None of those facts were in the request.
Try “Your olive Everyday Tote is still in your cart.” Add this preview: “Take another look, or pick up where you left off.” One names the item. The other adds a next step.
Shopify’s guide says to make the subject and preview work together. Read both with the email. If they promise a deal or guide, is it there?
Check claims against your store. An AI score is not proof.
3. Pick two clear choices
“Your tote is waiting” and “Your tote awaits” say the same thing. More drafts like those will not give you much to compare.
Try a plain reminder: “Your Everyday Tote is still in your cart.” Then try a question: “Back for that Everyday Tote?” Both fit this email.
You could use a known detail: “The olive tote you picked.” Check how each line looks in a phone inbox.
Skip “Still choosing your size?” if the email has no size help. Pick a line that makes the right promise.
4. Keep a note of what you learn
Save both subjects before a test. Write down why you chose them. Use similar groups. Keep the email, preview, deal and send time the same. This helps you compare just the subjects.
Check clicks and orders as well as opens. Apple Mail Privacy Protection can load an email before it is read. An open does not always mean a person read it.
Two orders for one draft and one for the other is a small clue. It is too soon to say “AI doubled our sales.”
Send yourself a copy first. Look for cut-off words. Check the preview. Try the button. Fix those issues before the test.
