Most brands stop automating the moment an order is placed - but the post-purchase window is one of the best opportunities to build loyalty and set up the next sale.
What a post-purchase flow should cover
- Order confirmation & shipping updates: Not just transactional - use them to reinforce your brand and set expectations.
- Product education: Tips for using or caring for what they bought, which reduces returns and support tickets.
- Review request: Timed after the product has likely arrived and been used, to maximize response rate.
- Replenishment or cross-sell: Timed to match typical usage cycles for consumable or complementary products.
Klaviyo for post-purchase
Klaviyo lets you branch flows by product category or purchase value, so a customer who bought a starter kit can get a different follow-up than one who bought a premium bundle.
Mailchimp for post-purchase
Mailchimp's product recommendation blocks make it easy to auto-populate cross-sell emails based on what a customer already purchased, without manually curating each send.
A simple starting flow
Begin with three emails: a branded shipping update, a review request 10-14 days after delivery, and a replenishment or cross-sell reminder timed to your product's typical usage cycle.
