Expansion revenue is the most efficient growth lever. No acquisition cost. The user already trusts your product. They just need the right nudge when their usage says they're ready.
When a user hits 80% of their plan limits, they're feeling the constraint. That's the perfect moment for an upgrade email — they already want more.
A free user who tries to access a pro feature is telling you they want it. Trigger an email explaining what they'd unlock.
When a user invites teammates or shares content, they're expanding usage. That's a natural upsell moment for team plans.
