The before and after email, for products whose proof is visual

The comparison happens before the reader has decided to read

A paragraph asks somebody to decide to start reading. A pair of photographs doesn't. The eye compares the two states before any conscious choice gets made, and that's why this format survives being opened on a phone, half read, at speed.

All of that goes the second the pair looks staged. Different lighting, a different angle, a suspiciously tidy second frame, and the reader stops looking at the result and starts hunting for the trick.

Customer pairs beat studio pairs, every time

Your own photography will be better lit and less convincing. A customer's kitchen, their patio, their van, their bad phone camera: all of it reads as real in a way a studio set never will.

1. Ask in the post purchase sequence, at the point the result would have happened, not the day the parcel arrived
2. Ask for both frames explicitly, because most people only think to photograph the after
3. Give one instruction that improves the pair, which is to stand in the same place both times
4. Get permission in writing in the same thread, and ask whether they mind their first name being used
5. Keep an archive with the product and the elapsed time recorded against each pair

The elapsed time matters more than anything else in that record. A result after one application and a result after six weeks are different claims, and the email has to say which one you're showing.

State the conditions, or the pair works against you

Every before and after email should carry the boring details. How long, how many applications, what else was involved, what the result doesn't cover. It feels like you're weakening the campaign. You're doing the opposite.

Readers in these categories have been shown doctored pairs for years and turn up suspicious. Naming the conditions is the fastest way to be the brand that isn't doing that, and it's the difference between a result people believe and one they scroll past.

It protects you too. A pair with no conditions attached is an implied promise about typical results, and typical is a word you have to be able to defend if anybody asks.

Stack them, don't slice them

Side by side halves are the default and they're the wrong call on a phone, where each image ends up too small to read. Stack the pair full width with a short label on each, or use one image with a clean vertical split where the subject is the same frame.

Those two are our own before and after, of a client's welcome email, not a product. The format's doing exactly what it does in a product campaign: the difference registers in about a second, and only then does anybody read the labels.

It's a campaign and it belongs in a flow

Run it as a campaign to browsers and lapsed subscribers, then lift the best pair into the automated sequence where the same doubt shows up. In most accounts that's the second or third email of the abandonment sequence, where the objection is whether the thing actually works.

The abandoned cart flow is where a proof pair earns most, because it's read by somebody who's already picked the product and is looking for a reason to go ahead. Patio Black Spot Removal is the account where this format does the heaviest lifting, for the obvious reason that the result is the entire product.

Count the pairs you already have

Search your inbox, your reviews and your social mentions for customer photographs, then count the usable pairs you've got today. Most brands in these categories are sitting on dozens and have used none of them, because nobody was ever made responsible for collecting them.

If the answer is none, the fix is one line added to the post purchase sequence asking for both frames. Six weeks later you've got a campaign. After that you've got one every month without asking again.
