Email sequence that earns each next open

Write a 5-email sequence for people who {{trigger, e.g. signed up but never activated}}.

Before writing, state for each email: the one thing the reader must feel or do, the reason they'd open it given the last one, and the reason it's fine if they ignore it.

Then write all five. Constraints: subject ≤45 chars with no curiosity gap the body doesn't pay off; first line never restates the subject; one idea and one link per email; under 140 words each; plain text; sign-off consistent.

Specifics: email 1 delivers value with no ask. Email 2 addresses the top objection directly. Email 3 shows a peer's concrete outcome with numbers. Email 4 removes friction (make the next step 60 seconds). Email 5 is a clean, unembarrassed last-call with an easy opt-down.

End with the send timing and the metric that would tell me each email is failing.
