Rejoiner is my favorite vendor to work with. From implementation to go-live and support, they'll take care of everything: idea generation, design, copy, coding, and technical support. Post launch, they're always willing to further enhance your remarketing campaign, always bringing new ideas to the table. Best of all, their product just works. The results from our campaign have been stellar.

When you consider how much you earn back compared to how much it costs to do email remarketing, it ends up being a no-brainer. Plus, Rejoiner brings you closer to the experience visitors have on your site by helping you to learn what people are thinking and why they’re not buying products. The additional contact with customers has only made it easier to offer an even higher level of customer service and to learn more about customer needs.
