- Define segmentation, targeting and personalisation as distinct steps
- Explain why the three steps happen in that order
- Recognise which step is broken when results disappoint
- Classify each step in a campaign you ran recently
Segmentation, targeting and personalisation are three different decisions, made in that order. Segmentation divides your customers into meaningful groups. Targeting decides which of those groups this campaign is for, and how much to invest in each. Personalisation adapts what each person actually sees. Blur them together and you get the worst of all three.
The reason the order matters is that each step depends on the quality of the one before. You cannot target well if the groups are mush. You cannot personalise well if you don't know who you're talking to. When a marketer says "our personalisation isn't working", the broken step is usually two doors down.
Step one: segmentation defines the options
Segmentation is analytical work. It happens before any campaign exists, and it produces a menu: named groups with definitions, sizes and behaviours. No message has been written. No budget has been spent. The customer base has simply been made legible.
Step two: targeting chooses from the menu
Targeting is a commercial decision. Given the segments and this season's goal, which groups get attention, and what is each worth? Notice what else targeting includes: choosing who not to contact. Leaving a group out of a campaign that would only dilute its message is often one of the most profitable decisions segments make possible, and it costs nothing.
Step three: personalisation adapts the message
Personalisation is creative and operational work: adapting content, offer, timing and channel to the recipient. Note what personalisation is not: putting a first name in the subject line. "Hi Sarah, here's 10% off everything" is a mass message wearing a name badge. Real personalisation changes the substance, because the segment tells you what this group cares about.
Targeting is the commercial choice: the goal is full-price furniture sales, so the budget goes behind the buyers and the browsers, and the greenhouse crowd is deliberately held back for their own campaign in February (greenhouse buyers shop early; his gut always knew it, and now the order dates agree).
His discount-only buyers would happily take 10% off furniture they'd browse anyway; leaving them out of a full-price campaign is one of the most profitable decisions his segments make possible, and it costs nothing.
Personalisation changes the substance: past furniture buyers get an early-access invitation to the new range, no discount attached (they've shown they'll pay full price; what they value is first pick), and the browsers get social proof and a first-purchase incentive, because the data says they're interested but hesitant.
Why the order pays
Same business, same season, three separate decisions, and each one is checkable on its own. If a campaign lands badly, you can ask which step failed: were the groups wrong (segmentation), was the choice wrong (targeting), or was the message wrong (personalisation)? A storewide blast never grants you that visibility; when it flops, it flops for reasons nobody can isolate.
A fashion retailer emails its full list: "Hi {first name}, our summer sale is on." Which step of the pipeline is this using?
Key takeaways
- Segmentation defines the groups, targeting chooses which groups to invest in, personalisation adapts what each person sees. The order is fixed.
- Each step depends on the previous one: poor segments make targeting a guess and personalisation a gimmick.
- Deciding not to contact a segment is a targeting decision, and often a profitable one.
- A first name in a subject line is not personalisation. Changing the substance of the message for each group is.
