Birchbox is the easiest way to discover and shop for beauty and grooming products by pairing a monthly subscription of personalized samples with relevant content and a curated online shop. Birchbox re-envisioned its mobile app as a shopping tool for subscribers who wanted to be able to shop anywhere, anytime, without waiting for a mobile site to load. Birchbox then launched a comprehensive push messaging strategy to support its app. In order to help develop, implement, automate and track its push notification strategy, Birchbox chooses Carnival by Sailthru. Here were their goals:

  • Increase visit frequency per user
  • Grow revenues for Birchbox’s online shop
  • Upsell engaged, high value customers
  • Advance mobile messaging with more personalization and segmentation



With Carnival by Sailthru, Birchbox was able to both expand and refine its push notification strategy. To ensure that the more-frequent messages remained relevant to customers, and to distinguish itself from other brands, Birchbox emphasized urgency and personalization. The complete solution allows Birchbox to:

  1. Segment push notifications alerts to customers to review samples, customize their subscription boxes, or take advantage of promotions
  2. Personalize the app homepage so that it reflects the status of a particular customer’s subscription cycle
  3. Add a customer’s name to push notifications to improve engagement
  4. Use customer response metrics and insights on push notification performance to inform strategy across the Birchbox website, mobile web and other channels
