The Opportunity

An app that automatically sends personalized welcome SMS messages to new opted-in subscribers, with segmentation and basic automation triggers. It fills the gap between Shopify’s limited native SMS capabilities and merchants’ need for a true onboarding flow.

"Merchants want an automated welcome SMS flow, but Shopify’s native tools are perceived as focused on transactional messages rather than marketing automations."
