our call
Start with Emarsys — highest vibe code, weakest moat.
Emarsys
Rebuilding basic transactional email logic or simple visual email builders is quick, but Emarsys functions as an enterprise Customer Data Platform (CDP) and deliverability manager. It handles millions of event ingestions, multi-channel push/SMS/email orchestrations, and complex compliance frameworks. Building the application shell is easy; replacing the deliverability reputation, ISP relations, and SAP ERP integrations is not.
