Buffer journey
Why this works
**Why this works.** The subject line gamifies an existing behavior (posting consistency) by quantifying it as a "streak," which triggers both pride and loss-aversion - users want to protect the number they've built, not reset it to zero. The pattern here is "make progress visible before asking for amplification"; you can lift it for any expand user email where you want existing power users to become advocates by first showing them the value they've already created.
