Expansion· Cross-sell Curious
Why this week, this cohort.
1,598 of your customers bought Slim Cotton Filters but not the SilverStick - Slim pipe they're designed for. They're one product away from the full setup.
These 1,598 people ordered Slim Cotton Filters - 100 Count once, but haven't bought the SilverStick - Slim pipe. Historical order data shows 4,118 customers bought both together, and 917 people moved from filters to the pipe in a later purchase. The industry benchmark for cross-sell flows is 2.5% conversion over 35 days. That's roughly 40 customers at $140 lifetime value each — the $2,240 line in your audit. This week, we send four emails to complete their setup.

Expansion · Cross-sell Curious
Four emails over 35 days to the same 1,598 customers, each reinforcing the natural pairing between Slim Cotton Filters and SilverStick - Slim. The first introduces the pipe as a logical next step. The second highlights use-case synergy. The third reinforces routine integration. The final touch reminds them of the missed opportunity. No discounts — the product pairing itself provides the value proposition.

Name campaigns and tag links the same way every time.
Two short codes that turn anonymous "clicks" into "clicks from week 1 touch 2." Without them, the scorecard at the end of the week can't tell which touch did the work.

Each row is a metric we'll track. Projected is what we believe this campaign will hit; benchmark is the industry-average comparison point. The gap (the lift column) is where the cohort-warming logic shows up — these aren't strangers, they're 3+ time buyers.
