Email and SMS

Automated SMS and multi-channel flows

Create SMS, MMS, and multi-channel flows (email and text) that are triggered off of each individual shopper’s behaviours and preferences—like browsing, cart abandonment, order history, order and shipping confirmations, form completions, and more.

  • Create flows quickly with our drag-and-drop flow builder
  • Combine email and SMS messages in the same flows
  • Use preference and behaviour-based splits
  • Stay safe with smart sending rules and quiet hours
  • Include dynamic product images from browse and shopping behaviour
  • Share a virtual contact card to increase brand recognition
Automation example: One week before expected order, send SMS if consented, otherwise send postcard if predicted lifetime value exceeds $100.

Customer database for ecommerce texting

Power your text marketing program with a robust customer database that includes each shoppers’ entire history of interactions with your website, products, emails, texts, and forms as well as data pulled in from hundreds of integrations. And use that data to create the targeted segments and personalised texts you need to drive sales.
