Case Study: Listia achieves 25% higher email deliverability and increased engagement with SendGrid

Listia Trades Poor Email Delivery for Increased Engagement and Conversion

Listia is a social online marketplace and mobile app where users buy, sell and bid on items using credits instead of cash, and it has grown to over 8 million users. Because the platform depends on email for bids, reminders and account activity, rapid growth (a 30% rise in monthly emails) led to blocks at Hotmail and Yahoo, blacklistings and roughly 20% of messages being blocked—hurting engagement and disrupting trades. An earlier switch to authsmtp.com didn’t provide the deliverability infrastructure, analytics or expert support the team needed.

Listia partnered with SendGrid, moving to a dedicated IP, implementing DKIM and gaining real-time analytics and deliverability expertise to monitor, test and resolve issues quickly. As a result, deliverability improved by 25%, engagement and conversion rates rose (signup verification emails increased by over 10%), and Listia achieved meaningful cost savings by outsourcing email delivery.
