Lightspeed is a cloud-based point-of-sale system and ecommerce platform that processes over $15 billion worth of transactions for independent retailers and restaurateurs every year. Founded in 2005, Lightspeed now serves more than 45,000 businesses across 101 countries.

Mathieu Martin, Cloud Infrastructure Architect, advises Lightspeed’s various product groups on implementing cloud-based technologies including email services. Mathieu also ensures that Lightspeed’s cloud operations run smoothly by troubleshooting and building feedback processes so the company can focus on innovating its product.

Our ecommerce platform generates millions of transactional emails per month. Our clients’ customers are able to know when their orders are being shipped or if they need to reset their passwords to our clients’ online store... email is a central part of interacting with our ecommerce platform.

Lightspeed’s ecommerce product originally sent email with a basic open-source mail transfer agent. Mathieu and his team discovered that some of their merchants’ unprotected email sign-up pages were being attacked by malicious parties who were trying to overwhelm their victims by flooding them with undesired emails.

These attacks resulted in a large mailbox provider in Europe blocking Lightspeed’s email. This meant that, for example, merchants and their customers weren’t receiving critical notifications about their online store’s activity, putting Lightspeed’s relationship with those clients at risk.

“It’s important for us to have our merchant’s emails delivered quickly and reliably,“ Mathieu says. “We needed to correct this issue as quickly as possible.”


In order to find the best solution for their clients, Mathieu and his team evaluated two other popular transactional email services. The team decided on SendGrid. Lightspeed already used SendGrid for the North American deployment of their ecommerce platform, and Mathieu was confident that SendGrid had the feature set to meet the needs of the European deployment.

Mathieu wanted to ensure that Lightspeed eCom’s email program would get started on the right foot so he elected to engage in an Implementation Services engagement with SendGrid’s email experts. In this customized consultation, SendGrid’s experts guided Lightspeed through the account setup process, focusing on:

  • IP configuration and warm up,
  • API and technical implementation,
  • DNS  authentication configuration, and more.

“It wasn’t just setting up a new system with just any MTA,” says Mathieu. “It was moving a workload of millions of emails per month to this new platform in a way that makes sense and avoids ramping up too quickly, which can look suspicious to spam protection tools.”


In addition to giving Lightspeed the exact architecture needed to bring their European traffic to SendGrid, SendGrid’s onboarding experts helped monitor sending while Mathieu and his team put a CAPTCHA in place to help clients protect against any future attacks.

With the help of SendGrid’s Onboarding Services team, Lightspeed experienced:

  • Improved IP reputations with an average delivery rate over 98% while maintaining an average unique open rate over 75%, signaling merchants’ customers are receiving wanted email.
  • 25x decrease in spam reports with malicious list attacks stopping entirely.
