our call

Start with Lootly — highest vibe code, weakest moat.

Gatsby

The core job—listening to Instagram webhooks, grabbing emails from DMs, and updating Klaviyo/Shopify—is trivial backend code. However, navigating Meta's App Review process, staying compliant with Messenger policies, and managing rate limits during viral bursts make running custom infrastructure a chore.

  • Email and phone collection flows via automated Instagram direct messages
  • Shopify customer metafield enrichment with Instagram handles and follower counts
  • Klaviyo profile property syncing and metric event dispatching
  • Basic social contact suppression and archiving to manage billable user tiers

what you lose

  • Pre-certified Meta Instagram Messaging App Review compliance.
  • Turnkey integrations with third-party loyalty software like LoyaltyLion, Smile.io, and Yotpo.
  • Dedicated Customer Success Manager for managing higher tier handle suppression strategy.
  • Native TikTok video tracking add-on infrastructure.
  • Out-of-the-box UI for custom DM sequence builder and template library.
