About Signals

Signals is a new iMessage revenue channel for DTC ecommerce brands that gets customers to buy again. After a purchase, we open a real two-way conversation over iMessage, the channel customers actually read and reply to, and turn it into repeat revenue. In A/B tests, that drives ~$30 in average incremental repeat revenue per conversation.
