Start with Rejoiner — highest vibe code, weakest moat.

While building a basic drag-and-drop flow builder connected to SendGrid and Twilio takes weeks, Listrak's real value lies in shared identity networks, enterprise deliverability ops, and regulatory compliance infrastructure. Replacing it requires managing dedicated IP pools, carrier shortcode registrations, and continuous identity graphs across high-volume traffic.
