FlexEngage

FlexEngage is a retail customer-engagement company that powered transactional and triggered customer communications for retailers and brands, including digital receipts, order and shipping notifications, and omnichannel messaging across email, SMS, and print. The company was backed by Bullpen Capital and was acquired by Narvar in 2019. This API Evangelist profile was surfaced from the Bullpen Capital portfolio; the public site (www.flexengage.com) is currently served behind CloudFront and returns HTTP 403 to automated clients, so no public developer/API surface could be captured during enrichment.

FlexEngage is profiled on the APIs.io network. Tagged areas include Company, Retail, Customer Engagement, Transactional Communications, and Messaging.
