In order to test the rendering of the email design, OpticsPlanet turned to Return Path's Inbox Preview solution which allows senders to preview email campaigns on the most up-to-date devices whether on mobile, webmail, or desktop platforms. At the same time, they needed to keep an eye on their inbox placement rates to ensure their IP address and domain reputations were in good shape. The Return Path Platform gave them this ability with the most accurate and comprehensive data regarding their deliverability.
