This summer, we’ve been celebrating the five-year anniversary of SendGrid. Part of that celebration has been looking at some of the major scaling milestones and accomplishments of our customers and the company through retrospectives, webcasts, and an infographic, all shared in part, below. 


A big part of helping our customers scale has been learning from our own growth.

Since graduating from TechStars, SendGrid has grown from 3 employees to 250 and from 0 emails sent to 273 billion. Throughout this time, we’ve learned that reliability, support, and providing a powerful infrastructure are critical to supporting large email volumes–2% of the world’s wanted mail. As such, we’ve grown to provide:

  • 24/7 global customer support via chat, email, and phone
  • 17 dedicated Technical Account Managers for high volume senders
  • 12 Developer Evangelists committed to making developers’ lives more awesome across the globe
  • 5 data centers for quick and reliable delivery
  • Over 650 physical servers and 1,100+ virtual machines to power your email

Scaling with Partnerships

Another component of providing scalability to our customers is aligning with strategic partners. In looking back on the past 5 years, our Director of Business Development, Laurence Trifon, shared some of his thoughts on the value that our 50+ industry partnerships provide our customers:

Email is a fundamental technology for virtually every website, mobile app, and business. Whether you’re a developer platform or a systems integrator, having an email solution to offer to your customers is important.

For our partners, working with SendGrid enhances their core offering, and helps them solve a need for their customers. On the flip side, our partners help SendGrid reach users that would otherwise be difficult or expensive for us to reach on our own – whether that’s enterprise developers, or users in specific geographies, or some other segment where our partners have more presence than we do today.

Scaling the Customer Experience

People have always been a priority at SendGrid—starting with our customers and our employees. So as SendGrid’s mail volume has grown, so has our people power. Sending large volumes of mail can be difficult, so to help simplify the process and make delivery as successful as possible, SendGrid has scaled its support resources in the form of our 24×7 support team, our expert deliverability, compliance, and developer relations teams, and our customer success team.

Our Director of Customer Success, Amy Mustoe, has helped develop our account management team over the past few years and in her retrospective, shared some interesting insights into how we help our high volume customers scale…by sometimes sending less mail!

Since email is still the main communication channel for businesses, if we help our customers become good email senders and build a strong reputation in the industry, it will only enhance their business. So, sometimes we’re telling our users to send less email. Our relationship with our customers is a long-term commitment—if they’re being smarter about the messages they’re sending, they’ll be more successful over the long term.

For more from Amy and what the future of Customer Success looks like at SendGrid, read her full post here. And to hear how our customers benefit not only from the attention of a dedicated technical account manager, but also from SendGrid’s technology, join us for a live webcast this Thursday, August 28th at 1pm ET with Commissions, Inc as they share how they’ve scaled from sending two thousand emails a month to tens of millions. They’ll be available to answer any questions you have, so we’d love to have you join us.

Looking Back

Finally, SendGrid’s founders have been the true foundation of our customers’ scalability. Their unwavering dedication to solving email deliverability is still at the core of our decision-making today.

Each of the founders took some time to share some insights into where this drive started and how it’s shaped our customers’ growth. Hear more from Isaac, Jose, and Tim in the their posts:
