Apollo.io journey
Why this works
**Why this works.** The subject line leads with a verb-plus-outcome ("Supercharge") rather than naming the tool, so existing users immediately understand what doing this expansion enables them to do, not just what they're installing. The pattern here is "outcome-first subject lines for feature adoption"; you can lift it for any expansion email where you want activated users to see the benefit before the mechanic.
