Case Study: Nextdoor achieves 99%+ email deliverability and faster scaling with Twilio SendGrid

How Nextdoor is leveraging SendGrid

Nextdoor, the free and private social network for neighborhoods, needed an email platform that could keep up with rapidly growing message volume as its email sends increased faster than member growth. Its in-house system and a smaller ESP led to engineering strain, delayed or duplicate messages, and recurring deliverability issues, so Nextdoor turned to Twilio’s SendGrid email service.

Twilio’s SendGrid gave Nextdoor a scalable, reliable email solution with expert support and proactive monitoring, reducing the burden on internal engineers. The results were strong: Nextdoor more than doubled its customer base, cut email management to less than one engineer’s time, reduced delivery latency by 95%, and maintained deliverability consistently above 99%.
