Email is central to’s operations, and it accounts for one third of the dollars raised by citizen donors. Over the last year, raised more than $63 million for classrooms in need, of which more than $10 million is attributed to their robust email program.

Beyond revenue, email is key to fostering and nurturing long-term relationships between donors and classrooms. has a database of over 1.4 million opt-in users and sends approximately 2 million emails per month (more during the back-to-school and holiday seasons).

Email serves as the main communication channel for Donors receive regular email updates on projects, thank you notes from teachers and students, as well as photos and progress reports. Donors are also notified of classroom projects that match their interests and geography as a way to foster the spirit of continued giving. Teachers use the platform to post, manage, and update their projects while communicating directly with donors on project status and results.

When it came time to change datacenters in 2012, they realized that they’d be leaving behind their email IPs, on which they’d established an excellent sender reputation over many years. They also realized that as the importance of email to their philanthropic mission grew, so did their sending volume.

At last, the technical challenges of managing their transactional email in-house had surpassed the expertise of their technical team. To avoid future constraints and a large in-house technical investment, began searching for a platform that was purpose-built to provide email infrastructure and deliverability as a service. In order to become their vendor of choice, this system would have to:

  • Enable to decouple their transactional email servers from their production servers, and provide the flexibility to host their email from anywhere
  • Provide more insights into their deliverability and response rates with clear and actionable statistics
  • Enable key transactional email functionality with minimal effort, such as DKIM, click-tracking, and bounce-tracking
  • Easily integrate with their existing platform
  • Provide hands-on support and advice in the areas of transactional email best practices, troubleshooting, prevention, and solvability


Solution evaluated six vendors, but SendGrid was the only provider that met their criteria.

  • Easy Integration: Whereas other provides required them to move or rebuild their email templates into their systems, SendGrid only required a quick SMTP and DNS configuration change to integrate.
  • Easy Configuration: Configuring their transactional email to follow best practices like DKIM signing and click-tracking simply required turning the feature on.
  • Easy Access to Email Statistics: Using the Event Webhook, could collect real-time email performance statistics in their own system. This enabled the reporting and analytics their Marketing and Product teams needed to manage and improve their transactional email.



This past school year, raised more than $63 million for classrooms in need, of which more than $10 million is attributed to their robust email program. This is due in part to their ability to better optimize and measure the effectiveness of their transactional email campaigns using real-time deliverability and response data.

For example, the team was able to reimagine their monthly project recommendation emails that are delivered to over one million donors. By experimenting creatively with the content, they went from raising $15,000 in donations to over $150,000 each month.

Additionally, the switch to SendGrid freed up valuable time for their engineers and product team. They no longer have to maintain a homegrown transactional email delivery solution and troubleshoot issues. Instead, they rely on the SendGrid platform and account management team to monitor, diagnose, and help fix potential delivery problems that may surface.

With a cloud-based email infrastructure in place, they no longer have to worry about moving servers or losing IPs should they choose to change where their systems are hosted.

Overall, with a database of over 1.4 million opt-in users, emails continue to achieve high delivery and response rates. Delivery rates now hover around 99% ensuring that both teachers and donors continue to receive the necessary communications that drive activity on the site and lend transparency to the organization.

Most importantly, team members can focus on what matters most—innovating in the non-profit space and connecting the community with classrooms in need.

Email is the heart and soul of our business. It drives meaningful connections between our 1,400,000 donors and teachers, and raises millions of dollars for high-need schools across America. We needed to partner with an email service provider that could ensure the delivery of our transactional emails, with minimal engineering overhead, to support the growth of these relationships between citizen donors and hardworking teachers. SendGrid was the only provider that had the email tools, expertise, and platform flexibility to let us put transactional email infrastructure on autopilot so we could fully focus on product and engineering challenges that are unique to our cause.
