Case Study: uSell achieves higher open rates and offline conversions with Dyspatch

How uSell achieved a 24.5% increase in open rate and 8.6% increase in revenue-generating offline conversions

uSell, an online marketplace for used electronics, wanted to improve its retention email campaign and increase its send-in rate after customers received prepaid shipping kits. They worked with Dyspatch, using Sendwithus transactional email testing to optimize the subject lines in emails sent to customers who had already agreed to sell their devices.

Dyspatch helped uSell run A/B tests on multiple subject line variants to encourage customers to complete their sales. The winning emails drove a 24.5% increase in open rate, a 7.5% increase in send-in rate, and later an 8.6% increase in revenue-generating offline conversions, showing that subject line optimization could directly improve transactional email performance.
