What a popup line is made of

A popup headline is the first line a shopper reads when the popup opens, and a working one names what they get in ten words or fewer, so a store giving 15 percent off writes 15% off your first order rather than Join our newsletter.

The lines are written from fixed frames, not by a language model, and the checklist is Nudgesmart’s own reading rubric rather than a published standard or a measurement of any store. For the colour of the button the line sits on, check its contrast.

Every line this page writes, and every line it grades, has the same four parts. The generator fills them from your offer, your store type and your tone; the grader reads them back and says which part is missing.

Headline
The biggest words on the popup. It carries the offer, because it is often the only line read before the shopper decides to stay or close. Ten words is a ceiling, not a target.
Sub-headline
The second read. It says how the offer arrives and what the shopper gives for it, usually an email address, and it is where detail goes when the headline would otherwise run long.
Button label
The last line before a decision. It opens with a verb and ends with the reward, so the shopper knows what pressing it does. Submit and Sign up describe the form, not the reward.
Decline line
The plain way to say no, such as No thanks. A popup with a visible way out reads as an offer. One without reads as a wall, and the shopper finds the exit on the browser instead.
Angle
Which part of the offer the headline leads with: the offer itself, the benefit to the shopper, or a reason to act now. The generator writes one of each so you can hear the difference.

Seven popup headlines, read against the checklist

Illustrative lines, not customer data and not a ranking of what converts. Each row is graded by the same checklist the grader above runs, and the fix column is the first thing it would change.

Row three is the easiest one to write by accident. It names a real offer, carries a number and has a good button, and it still misses, because it tries to say everything in the headline. The same offer in five words, row four, clears every check.

What a checklist cannot tell you about a headline

Clearing the checklist is not the same as converting

The checks are things a headline can be read for: length, a named offer, specificity, a verb on the button and a way out. They say nothing about whether your shoppers want the offer, which matters more than any wording.

The offer does more work than the words

A clear line about an offer nobody wants still loses to a clumsy line about one they do. If a sharper headline changes nothing, look at the offer and at when the popup opens before rewriting the copy again.

Timing and audience sit outside the copy

The same headline shown on arrival, on the way out and to a returning customer is read three different ways. A headline that is right for a first-time visitor can be wrong for someone with items already in the cart.

The preview uses a ready-made design, not yours

The line is shown on a template so you can see it at a real phone size. Your own design will break lines differently, and a long word in a large display face can wrap where this one did not.

Popup headline questions

What makes a good popup headline?

It names what the shopper gets, carries a number or a concrete thing they can picture, and fits in about ten words. 15% off your first order does all three. Join our newsletter does none of them, because it asks for something and offers nothing back.

Does this use AI to write the headlines?

No. Every line comes from hand-written frames filled in with your offer, your store type and your tone, so the same choices always give the same lines and a shared link shows exactly what you saw. Nothing you type is sent anywhere.

How long should a popup headline be?

Ten words and about sixty characters is the ceiling this checklist uses, because on a phone a longer headline wraps onto three or four lines and pushes the button below the first screen. If the offer needs more words, the extra detail belongs in the sub-headline.

What should the popup button say instead of Submit?

What the shopper gets, opened with a verb: Get my 15% off, Send me the guide, Claim free shipping. Two to five words keeps it on one line on a phone. Submit, Sign up and Subscribe describe the form rather than the reward, and adding a word such as now or today, as in Sign up now or Join now, does not change that.

Is the grade a prediction of my signup rate?

No. It is a reading checklist, not a benchmark, and it is not built from anyone else’s results. A headline can clear every check and still miss if the offer is wrong for your shoppers or the popup opens at the wrong moment. The only rate that settles it is the one your own store records.

Should every popup have an offer?

No, but a popup without one has to sell the emails themselves, so the headline has to promise something specific about them: a weekly first look, restock notices, a guide. The no offer lines here are written that way, and they work harder than a discount line does.
