Case Study: Overjoy scales AI sales agents with Nylas Email API

How Overjoy Runs AI Sales Agents on One Email Integration

Overjoy, an AI-powered wholesale CRM for consumer packaged goods brands, faced the challenge of reliably accessing thousands of its users' email inboxes to power its AI sales agents. The non-technical nature of its users required a simple, one-click connection process, while building and maintaining the necessary email infrastructure for multiple providers would have diverted its small engineering team from its core AI development. To solve this, Overjoy implemented the Nylas Email API with Hosted Authentication.

Nylas provided a single integration that unified access to Gmail, Microsoft, and IMAP inboxes. This solution allowed non-technical founders to connect their inboxes with one click and ensured reliable, behind-the-scenes token management. As a result, Overjoy scaled to several thousand connected inboxes with no added infrastructure work, experiencing 58% growth in connections in just two months. This enabled its AI agents to automate prospecting and order processing, directly leading to customers generating hundreds of orders and tens of thousands of dollars in new revenue.
