Email Copywriting Formulas: PAS, AIDA, and 7 More That Work
Nine structures with the situation each one suits, plus the two that stop working when the reader already knows you.
On this page
The short version
- Formulas are scaffolding for a first draft, not a structure to ship. Their value is that they stop you starting from a blank page.
- Two of the most-taught formulas stop working on a warm list, because they assume the reader needs convincing that a problem exists.
- Pick the formula from what the reader already knows, not from which one you find most persuasive.
Copywriting formulas are compressed advice about the order information should arrive in. That is genuinely useful, and it is also why using one without asking whether its assumptions hold produces email that feels off in a way nobody can name.
Every formula below assumes something about the reader's starting position. Match the assumption and the formula helps. Miss it and the email argues for something the reader had already accepted three paragraphs ago.
Nine formulas and what each assumes
| Formula | Order | Assumes the reader |
|---|---|---|
| PAS | Problem, agitate, solution | Has not fully felt the problem |
| AIDA | Attention, interest, desire, action | Does not know you |
| BAB | Before, after, bridge | Can picture a better state |
| 4Ps | Picture, promise, prove, push | Responds to a vivid outcome |
| PASTOR | Problem, amplify, story, testimony, offer, response | Needs social proof to move |
| FAB | Features, advantages, benefits | Is comparing specifications |
| SLAP | Stop, look, act, purchase | Is on a short, impulse decision |
| QUEST | Qualify, understand, educate, stimulate, transition | May not be the right buyer |
| Inverted pyramid | Conclusion, support, detail | Is scanning and may not finish |
The last row is the one borrowed from journalism rather than direct response, and it is the best default for email specifically, because it is the only one designed for a reader who may stop at any point.
The two that fail on a warm list
PAS and AIDA both open by establishing something the reader may already believe. PAS spends its first two movements making a problem feel urgent; AIDA spends its first two winning attention and interest. Both are built for cold traffic.
Sent to a subscriber who has read you for a year, PAS reads as being told about your own situation by someone who was not there, and AIDA reads as an introduction from a sender you already know. The reader does not think 'wrong formula' — they think the email is patronising, which is a harder problem to diagnose.
The adaptation is simple: on a warm list, start at the third movement. PAS becomes the solution with the problem stated in one line. AIDA becomes desire and action.
PAS to a cold reader and a warm one
Cold — full PAS
The problem needs establishing
- Problem: your emails may not be reaching the inbox
- Agitate: what that costs, and why nobody tells you
- Solution: the three records that fix it
- Works, because the reader may not know the problem exists
Warm — start at the solution
The problem is shared context
- One line: you already know placement is the constraint
- Solution: the three records, written out
- Support: what changed when we did it
- Works, because it does not re-argue a settled point
Why the inverted pyramid suits email best
Every other formula on the list assumes the reader continues to the end. The inverted pyramid assumes the opposite: it puts the conclusion first, then the support, then the detail, so a reader who stops after two lines still leaves with the point.
That matches the reality of an inbox more closely than any direct-response structure, and it is why the front-loading rule keeps reappearing in email advice under different names. It is not a stylistic preference; it is the pyramid.
Choosing in practice
Three questions settle it. Does the reader know you? Does the reader already accept the problem? Is the decision considered or impulsive?
Cold, problem unrecognised, considered decision — PAS or QUEST. Cold, impulsive — SLAP. Warm, problem accepted — inverted pyramid, every time. Warm, comparing options — FAB, because at that point the reader wants specifications rather than persuasion.
Using a formula well
- The formula's assumption about the reader matches your actual list
- No paragraph exists purely to satisfy a step
- The structure is not visible in the finished email
- On a warm list, the problem is stated once rather than argued
- The first two lines carry the point regardless of which formula was used
Frequently asked questions
Which formula performs best?
The question does not resolve, because the formulas suit different reader states and published comparisons rarely control for that. The one that fits your reader's starting position beats the one with the better reputation.
Can I mix formulas in one email?
In practice most good emails do, and unconsciously. Deliberately stitching two together usually produces repetition, because their middle movements overlap.
Are formulas useful for newsletters as well as sales emails?
The inverted pyramid is. The direct-response formulas assume a single conversion goal, which a digest does not have, and forcing one on a newsletter is how newsletters end up sounding like adverts.
