What is Omnisend?
Omnisend is an ecommerce-first email and SMS marketing platform. Instead of general email marketing bolted onto a store, it's designed around ecommerce behavior — cart abandonment, browse abandonment, welcome flows, and win-back campaigns that trigger from real store events.
Its standout strength is pre-built automation flows. Popular ecommerce journeys like abandoned cart recovery and post-purchase sequences are templates you can activate in minutes, with a drag-and-drop visual builder for customization.
