How a Retailer Automates Customer Follow-ups with Klaviyo and Notion

The Problem: Customers Who Buy Only Once

Pierre, owner of a fine grocery store in Bordeaux, had built a base of 1,200 customers over 3 years. Only 18% were regular buyers. McKinsey (2024): acquiring a new customer costs 5-7x more than retaining an existing one. Retailers with automated follow-ups increase retention by 25-35%.

The Klaviyo + Notion Architecture

Notion: centralized customer database (contact info, last purchase date, products bought, total spent, frequency, preferences/tags).

Klaviyo: automated email and SMS marketing tool (advanced segmentation, professional templates, detailed analytics, free up to 500 contacts).

Make: syncs Notion -> Klaviyo automatically (new customers, purchases, preference tags).

4 Follow-up Sequences That Work

1. Welcome sequence: new customer trigger. Emails at D+0, D+7, D+30. 90-day repurchase rate: 34% vs 12% without sequence.

2. Inactive customer re-engagement: no purchase for 90 days. "We miss you!" + product restocked notification + exclusive 15% off. Reactivation rate: 18% (vs 3% without).

3. Birthday email: personalized surprise offer. Open rate: 65% (vs 22% standard), conversion: 31%.

4. Smart cross-sell: triggered by specific product purchase. Cheese buyer -> wine/charcuterie sequence. Japanese tea buyer -> cups/teapots sequence. Cross-sell conversion: 14%.

Gartner (2024): retail businesses implementing all 4 sequences increase revenue by 19-27% without additional sales effort.
