What changes

Structured onboarding drips are often associated with a 10–25% relative lift in week-1 activation versus no lifecycle email.

When this tends to work

  • Conditions similar to: SaaS with defined activation milestone, self-serve users, 2022–2025
  • You can measure Week-1 product activation rate reliably
  • The intervention is implemented consistently, not half-measured

When to be careful

  • Your audience or product differs materially from the cited context
  • Compliance costs or second-order effects outweigh the lift
  • Evidence label is ab_test—treat wide ranges as planning bands, not promises

Practical takeaway

Use the cited range for prioritization and test design. Verify against your own data before scaling.
