PAS vs AIDA vs BAB, in short: PAS (Problem, Agitate, Solution) starts from a pain the buyer already feels. AIDA (Attention, Interest, Desire, Action) starts from a hook and builds interest step by step, so it suits buyers who have not noticed the problem yet. BAB (Before, After, Bridge) contrasts today with a better state and suits buyers who think in outcomes. All three are structures, not templates: they decide the order of your sentences, not the words.
Below you will find the three frameworks in one table, the difference between PAS and AIDA, and the same first email to a distributor written in each structure.
| Stands for | Use it when | Watch out for | |
|---|---|---|---|
| PAS | Problem, Agitate, Solution | The buyer knows the problem but has not acted | Agitation that sounds like a threat |
| AIDA | Attention, Interest, Desire, Action | The buyer may not see the problem yet | Four steps make a long first email |
| BAB | Before, After, Bridge | The buyer cares about outcomes and change | An "after" you cannot back up |
What is the difference between PAS and AIDA?
The main difference is where the email starts. PAS opens with a problem the reader recognises and makes it feel urgent before offering a way out. AIDA opens with something that earns attention, then adds a reason to keep reading, then a benefit, then the ask.
PAS has three steps and works on the reader's dissatisfaction, which is why it pairs well with loss framing: people tend to weigh what they stand to lose more heavily than an equal gain. AIDA has four steps and does not need a negative starting point, so it is the safer choice when you are not sure the buyer feels any pain at all.
In practice, PAS is easier to keep short. A first email has room for four or five sentences (see why long first emails get ignored), and AIDA's four stages compete for that space. In a short email, AIDA often ends up as PAS with a hook in front.
One product, three first emails
To compare the frameworks fairly, the three examples below use the same situation: a manufacturer of stainless steel commercial kitchen equipment writes a first email to a distributor that sells to restaurants. The company, the people and the details are invented for illustration.
PAS (Problem, Agitate, Solution)
Problem: name a specific difficulty the buyer faces. Agitate: show what it costs them if it continues. Solution: present your offer as one way out, with one ask.
PAS email example (fictional):
"Hi Anna,
Your site lists custom-size prep tables, and custom sizes are usually where lead times slip. (Problem)
When a restaurant opening waits on one table, the delay lands on you, not on the factory. (Agitate)
We build stainless prep tables and sinks to drawing, and we confirm the delivery date with the quote. (Solution)
Would a price sheet for your three most requested sizes be useful?
Mehmet"
Keep the agitation factual. With B2B buyers, a calm description of the consequence works better than drama, and it must be true for their business, which is why the problem should come from something you saw on their website or catalogue.
AIDA (Attention, Interest, Desire, Action)
Attention: open with something specific to them. Interest: add a relevant fact about your offer. Desire: show what it changes for them. Action: one low-effort next step.
AIDA email example (fictional):
"Hi Anna,
I saw you added a line of bar equipment this year. (Attention)
We make the stainless underbar sinks and ice bins that usually go into the same projects. (Interest)
Offering both from one quote means your customers deal with one supplier for the whole bar. (Desire)
Shall I send our catalogue with dimensions? (Action)
Mehmet"
Notice that there is no problem in this email. AIDA lets you write to a buyer who is happy with their current suppliers, which PAS cannot do without sounding forced.
BAB (Before, After, Bridge)
Before: describe their current situation. After: describe the better situation. Bridge: show how your offer connects the two.
BAB email example (fictional):
"Hi Anna,
Today, a full kitchen fit-out probably means separate orders for tables, sinks and shelving, each with its own lead time. (Before)
One order and one delivery date for all the stainless parts would make project planning simpler. (After)
We produce all three to drawing in one factory and ship them together. (Bridge)
Is a combined quote for your next project worth a look?
Mehmet"
BAB is only as strong as your "after". If you cannot deliver the better state you describe, the buyer will find out at the first order. Describe an outcome your product actually produces.
Which framework should you use for a first export email?
Decide from what you know about the buyer, not from which framework you like:
You can see a problem on their site (long lead times mentioned, a product gap, a supplier change): use PAS.
You see a fit but no problem (they sell products next to yours, they recently entered a category): use AIDA, kept to four short sentences.
The reader is an owner or manager who thinks in projects and results: use BAB.
Whichever you choose, end with one clear ask. A first email to a supplier-screening buyer has one job: getting a reply. What European purchasing managers look for in that first message is covered in first contact with an EU buyer.
Using the frameworks in the buyer's language
The structure survives translation better than the wording does. A PAS email translated word by word into German or Japanese can read as pushy, because the agitation step carries tone. Keep the order of ideas, and adjust how direct each sentence is for the culture you are writing to (see first contact across cultures).
This is also where the research matters more than the framework. Each step needs a fact about the buyer: the problem in PAS, the hook in AIDA, the "before" in BAB. Outfound researches each company on the live web, shows the evidence with sources, and drafts the first email in the buyer's language for you to approve, so the framework has real material to work with.
Can you mix PAS, AIDA and BAB?
Yes. The frameworks overlap, and real emails often combine them:
PAS + social proof: add one line about a similar customer after the solution.
AIDA with a PAS core: use the attention line as a hook, then run problem and solution.
BAB across a sequence: the first email shows "before" and "after", a follow-up delivers the bridge with a catalogue or sample offer (see the 4-email sequence).
Common mistakes
1. Skipping the hook
Do not open with your company history. Earn attention first with something specific to the buyer.
2. Agitation that turns into pressure
In PAS the agitate step creates urgency. Too mild and there is no reason to reply; too strong and it reads as a threat. One factual sentence about the consequence is usually enough.
3. More than one ask
Catalogue, call and price list in the same email give the reader three decisions instead of one.
4. Features instead of outcomes
Do not list what your product has. Say what it changes for the buyer and their customers.
PAS, AIDA and BAB templates
PAS template
"Hi [Name], [Problem you saw in their business]. [Agitate: what it costs them]. [Solution: how you solve it]. [One ask]?"
AIDA template
"Hi [Name], [Attention: something specific to them]. [Interest: a relevant fact about your offer]. [Desire: what it changes for them]. [Action: one next step]?"
BAB template
"Hi [Name], Today, [Before: their current situation]. [After: the better situation]. [Bridge: how your offer gets them there]. [One ask]?"
Frequently asked questions
Is PAS better than AIDA for cold email?
Neither is better in general. PAS fits when the buyer already feels the problem and it keeps the email short. AIDA fits when there is no visible problem and you need to create interest first.
What does BAB stand for in copywriting?
BAB stands for Before, After, Bridge: the reader's current situation, the better situation, and the step that connects them, which is your offer.
Can you use PAS in a follow-up email?
Yes. A follow-up can restate the problem from a different angle or add a new consequence, then repeat the same single ask. Keep it shorter than the first email.
How is FAB different from PAS and AIDA?
FAB stands for Features, Advantages, Benefits. It describes the product rather than the buyer's situation, so it works better inside a catalogue, a quote or a reply to a buyer who asked for details than in a first email.
Frameworks are thinking tools, not formulas. Start with the one that matches what you know about the buyer, write it in four or five sentences, and let the facts about their business do the persuading.
