Who it fits (our reading of its own pages; opinion)

From its own pages, Rejoiner is written for ecommerce businesses that want marketing automation for email, text messaging and direct mail, with a drag-n-drop email builder, a visual journey builder and segmented, multi-stage abandonment journeys. Its case studies name brands such as Peak Design, Big Chill Appliances, Momentous, Mother Dirt, A.T. Cross, KIKO and AuthenTEAK, so the pages point to established ecommerce brands across several categories. The problems it takes on include cart abandonment, timed reorder emails for consumable SKUs, subscription revenue, deliverability monitoring and dedicated sending infrastructure for high-volume senders. It speaks to marketers who feel overwhelmed trying to do it all, managing segmentation, automations and creative alone. A client can use the platform on its own, take a service with bi-weekly account reviews, performance reporting and optimization recommendations, or hand over content strategy, copywriting, design, email development and campaign deployment for a hands-off, managed approach.

What Rejoiner does, from its own pages

Rejoiner is a remote-first technology company that builds email marketing software and provides a range of email marketing services to ecommerce brands. Its homepage describes software and services for email, SMS and direct mail. Its pricing page describes marketing automation for ecommerce businesses.

On the services side, its pricing page names two optional packages. Its agency page lists audience health, strategy, copywriting, design, development, performance monitoring, and testing and optimization as its process.

These figures are the agency's own claims.
