Slack journey
Why this works
**Why this works.** The subject line leads with the discount discount (50% off) as the primary hook, then tucks the feature benefit (AI notes) as secondary proof that the upgrade delivers new value beyond just price-cutting, so users feel they're gaining capability, not just saving money. The pattern here is "anchor with incentive, validate with feature"; you can lift it for any expand user email where you want existing customers to upgrade and need to overcome the inertia of staying on their current plan.
