CartGhost

CartGhost is going after the abandoned cart problem through WhatsApp instead of email — which is honestly the move for merchants in Europe, Latin America, and Asia where WhatsApp has open rates that email cannot touch. The tool identifies carts in real-time and sends AI-powered conversational messages that let customers actually reply and ask questions mid-checkout, which is a way more natural loop than just screaming "complete your purchase" in a blast email. Free tier is solid for indie founders testing it out, and the two-way communication angle means you're not just yelling into the void — customers can actually interact. I low-key wish I'd thought of this first.
