Case Study: Gwynnie Bee boosts engagement and returns with Mailchimp

Stitching Together Data with Gwynnie Bee

Gwynnie Bee, a subscription clothing service for plus-size fashion, needed a better way to nurture prospects and customers without spending time creating a full email campaign every day. The company, which is highly data-driven, wanted to move beyond one-off A/B tests and connect with people based on where they were in their journey.

Using Mailchimp’s automation workflows, Gwynnie Bee sent targeted emails based on behavioral data and segmented users by lifecycle stage, such as recent cancellations. Mailchimp helped the team deliver editorial content, run “flock to unlock” promotions, and optimize for mobile-first design, which lifted engagement by 20% and helped win back users through more relevant, personalized messaging.
