The problem isn't your email sequence. You're emailing maybe 15% of actual abandoners because guest checkouts and iOS users are invisible to you. Think about it - someone adds to cart on Instagram browser, gets distracted, comes back through Google three hours later. Your system has no idea it's the same person. They complete the purchase and you think they're a new customer, not a recovered cart. Meanwhile you're obsessing over email timing for the tiny fraction you can actually track. Your 22% open rate means your emails are fine. The issue is you're missing 85% of abandoned carts entirely. Safari deletes cookies after seven days. iOS blocks most tracking. Guest checkouts leave no trail. Someone abandons on mobile Monday, buys on desktop Tuesday, and you have no idea they're connected. You think you have a 3% recovery rate when you actually might have 20% - you just can't see it. We discovered through https://apps.shopify.com/pen-and-paper that most stores are missing 85% of their abandoned cart opportunities because of identity resolution failures, not email optimization problems. The automation platform won't fix this. ActiveCampaign can't email people you can't identify. Fix the tracking first, then worry about sequences.
