Case Study: Foursquare achieves 96% inbox placement and saves engineering resources with SendGrid

SendGrid Becomes the Mayor of foursquare

Foursquare, the location-based mobile platform that helps users check in, earn rewards and connect with friends, was sending over 2 million emails per day (roughly 60 million per month) to notify users about friend activity and Mayorships. Rapid database growth exposed limits in their in-house email system and expertise, causing delivery delays, user complaints and blacklistings that threatened real-time engagement.

Foursquare outsourced transactional email to SendGrid, integrating in minutes, moving to a dedicated IP and adding deliverability alerts and analytics. Inbox placement rose to 96%, engineers were freed to focus on the core product, and the company gained proactive monitoring and cost savings in engineering resources.
