If you’re going to be sending a lot of email, you can be comfortable that SendGrid can handle the load. SendGrid works, and it works at scale.

Summary

Nextdoor is the free and private social network for neighborhoods. On Nextdoor, neighbors create private websites for their neighborhoods where they can ask questions, get to know one another, and exchange local advice and recommendations. The company’s mission is to use the power of technology to build stronger and safer neighborhoods. As Alex Karweit, Engineering Lead at Nextdoor says, “While we can now easily connect with those thousands of miles away, we've lost the connection with the community right in front of us—our neighborhood. Nextdoor is helping revive the local community connection and brings people together. Our platform helps you find that last minute babysitter, get a recommendation on a trusted roofer, or simply meet new people with similar interests.” Since its inception a little more than three years ago, Nextdoor has seen incredible growth and adoption. Today, the company provides a communication platform to more than 69,000 communities in the US.

Challenge

Nextdoor is a many-to-many communication platform that’s using email as its primary method of notifying users. Because of the nature of how communication works, email sending volume is growing very fast—50% faster than their member growth. When each member is getting multiple notifications about their neighborhood, it means Nextdoor needs an email platform that can grow with their needs. Originally, Nextdoor created an email solution in-house, and then moved to a small email provider. Unfortunately, both of these solutions presented a number of challenges: —Numerous employees were responsible for keeping their email program afloat. —Messages were constantly being delayed, going undelivered, or being sent multiple times. —Issues and outages would arise without experts to help correct them. In light of those challenges, Nextdoor re-evaluated what they wanted for their email program, and decided they needed a more reliable and scalable solution that didn’t require so much work from internal engineers.

Solution

SendGrid was already highly regarded internally, but after evaluating SendGrid capabilities, Nextdoor chose to move their email to SendGrid for a few different reasons: —They’re no longer the biggest fish in the pond with a small email service provider. SendGrid has sent over 450 billion emails since its inception, so Nextdoor knows they’re not pushing the envelope of what SendGrid can do. —Realizing they could go to their SendGrid Customer Success Manager, with any problems to help them out and get them back to moving email, Nextdoor realized SendGrid was the right fit. —They could rely on SendGrid to deliver their email correctly, instead of having their engineers spend time managing it like they did with other companies. This allowed Nextdoor to focus on making their product better.

Results

Since moving their email, SendGrid has been instrumental in scaling their email program to meet the needs of Nextdoor users. Not only have they more than doubled their customer base and email volume, they’re now sending millions of additional emails. Nextdoor has extremely high deliverability, high open rates, high clicks, and very low spam reports. SendGrid has been able to provide Nextdoor with:
  • Deliverability rates that are consistently above 99%.
  • Faster delivery by cutting delivery latency by 95%.
  • Reliable scalability that handles all the email they want to send.
  • Less need for dedicated engineers—their email program went from requiring 4 full-time engineers to needing less than one.
SendGrid provides an email solution that works consistently without problems, but should they arise, Nextdoor is now able to contact someone to help troubleshoot.
