Snapchat prospecting and existing-customer campaigns serve different jobs. Prospecting seeks new qualified people; a customer campaign may re-engage known buyers or encourage a next purchase. Compare them with separate audiences, offers and outcome definitions instead of reading one blended ROAS number.
Decision checklist
| Step | Practical check |
|---|---|
| Define membership | Document audience source, recency and exclusions. |
| Choose the action | Set new-customer and repeat-customer outcomes separately. |
| Check overlap | Review available reach and exclusion logic before launch. |
| Compare economics | Use verified orders, margins and acquisition costs. |
How to apply it
Write two test briefs. The prospecting brief states who has not interacted with the business and what first action is realistic; the customer brief states which first-party audience may be used and why the offer is relevant. Snapchat supports retargeting with Pixel and other custom audiences, but audience size and privacy rules matter. Check that consent and platform policy allow the chosen data use. Report results in separate rows, then compare incremental business value where the evidence permits. Keep exclusions and recency windows in the saved setup so a later comparison is fair.
Worked example
Synthetic UAE accessories shop spends AED 1,000 on broad discovery and AED 400 on past-site-visitor re-engagement. The latter shows lower attributed cost per purchase but includes existing buyers and has a small pool. The team does not call it “better acquisition.” It reconciles new and repeat orders, then tests excluding recent purchasers from the next visitor campaign.
Limits to keep in mind
Retargeting can capture demand created elsewhere, and small audiences can saturate quickly. Platform attribution alone does not measure incremental lift.
Review checklist
- Are prospecting and customer membership rules explicit?
- Are new and repeat outcomes separate?
- Is audience use permitted and measured with appropriate limits?
Common question
Should all budget go to the lower CPA audience?
No. A lower reported CPA can reflect existing demand and limited scale; judge each campaign by its assigned role.
