Customer expectations have shifted dramatically. A reply that arrives in 4 hours no longer feels acceptable when competitors respond in under 5 minutes. We analysed 18 million emails processed through Retenza across 2,400+ Shopify stores to understand how AI is reshaping what good support looks like.

The numbers behind the shift

Before adopting AI-assisted support, the median Shopify store in our dataset had a first-response time of 3.8 hours. After switching on Retenza's auto-reply mode, that number dropped to 4 minutes β€” a 98% reduction. More surprisingly, CSAT scores went up, not down. Customers don't care whether a human or an AI answered their question; they care whether their question was answered quickly and accurately.

What AI handles best

Order status inquiries, refund status checks, shipping delay explanations, and basic product questions now represent 71% of all incoming support emails for the typical Shopify store. These are precisely the tickets that AI handles with the highest confidence β€” they require accurate, specific data (pulled from Shopify in real time) but follow predictable patterns. Our model achieves 96.4% satisfaction rates on these categories.

Where humans still win

Complex complaints, escalations, unusual refund disputes, and anything involving genuine empathy at scale still benefit from a human touch. Retenza's confidence scoring is specifically designed to route these to agents. The goal isn't to remove humans β€” it's to free them for the work that actually requires their judgement.

What comes next

Voice support, WhatsApp, and Instagram DMs are the next frontiers. The same intent detection and Shopify data layer that powers email replies will extend naturally to these channels. Expect to see Retenza expand beyond email over the coming months.
