Email is a powerful driver for ecommerce. Not long ago, eBay sent standard “batch-and-blast” emails with hand-authored targeting criteria for each of their marketing campaigns.

While the batch-and-blast approach worked well enough for eBay’s peers in ecommerce, Alex knew that eBay could provide even more value for customers by treating them as individuals with true 1:1 personalization.

eBay committed to a differentiated experience in email, setting a high bar for their email program:

  • Each offer to a customer would be driven by an up-to-the-minute understanding of the products and services the customer had shown interest in, and how other customers were responding to similar offerings.
  • eBay would never direct a customer to an expired deal.


After evaluating multiple off-the-shelf solutions, Alex and his team selected an in-house targeting and personalization CRM system built on top of SendGrid. eBay’s innovations included:

  • A machine learning model to target customers with a built-in feedback loop to adjust recommendations quickly by testing how a subset of customers reacts to the recommendation. If the click-through rate is higher or lower than expected, the tool increases or decreases that product’s visibility in real-time for other customers.
  • Open-time rendering of email content so that product recommendations are personal and relevant based on the latest customer activity and product availability data.

To accomplish this experience, eBay leverages engagement data from its CRM and SendGrid’s real-time email event webhooks. eBay’s email system also depends on SendGrid’s reliable infrastructure to send an incredible amount of email, scaling seamlessly to one billion emails in four months.


Now instead of hundreds of small, uncoordinated campaigns each month, eBay houses a small set of “flagship” campaigns comprising one or more real-time, personalized offers. Each of the offers is selected upon the machine-learned model which uses real-time data, resulting in significant improvements in both click-through and sales driven by emails.
