Your patients are not abandoning shopping carts — they are postponing treatment plans. Klaviyo's abandoned cart email generates millions in recovered revenue for e-commerce stores. But your dental practice is not an e-commerce store. The triggers, the data model, and the entire architecture are designed for a business type you do not operate.
TL;DR
Klaviyo (free-$150+/month) is the gold standard for e-commerce email — abandoned cart recovery, browse behavior triggers, and product recommendation engines. Service businesses do not have carts, catalogs, or SKUs. They have appointments, treatment plans, and provider availability. Optimal.dev's AI understands service-business data natively.
E-Commerce Engine vs. Service-Business Engine
Klaviyo's entire intelligence layer is built on shopping behavior: which products a customer viewed, what they added to cart, what they purchased, and what they might purchase next. These signals do not exist in service businesses. A law firm has no product catalog. A dental practice does not have browse behavior.
Key Insight: Klaviyo's abandoned cart flow recovers 5-10% of lost e-commerce revenue. The service-business equivalent — following up on unscheduled treatment plans — requires an entirely different data model. A patient who was quoted for a crown and did not book needs a different message than a shopper who left sneakers in their cart.
The mismatch runs deeper than triggers. Klaviyo segments audiences by purchase frequency, average order value, and product affinity. Service businesses segment by appointment recency, treatment type, provider preference, and insurance coverage. Forcing service-business data into Klaviyo's e-commerce schema means losing the segmentation intelligence that drives campaign performance.

Service-Business Email Triggers That Klaviyo Cannot Build
The highest-value email triggers for service businesses are invisible to Klaviyo because they live in CRM and scheduling data that Klaviyo does not have:
Treatment Plan Follow-Up: A patient received a $4,000 treatment plan for implants and has not scheduled. The AI sends a personalized follow-up at day 7, day 21, and day 45 — each with different messaging angles (financing options, testimonials from similar cases, limited-time consultation offer). Klaviyo has no concept of "treatment plans."
Reactivation by Service Type: A patient who has not had a cleaning in 8 months gets a different reactivation email than one who is 18 months overdue. The urgency, messaging, and offer should escalate. Optimal.dev's AI reads the CRM timeline and adjusts automatically.
Provider-Specific Recall: If Dr. Chen is leaving the practice, patients assigned to her need a warm handoff email introducing their new provider. This requires provider-patient relationship data that Klaviyo cannot access.
Post-Visit Sentiment Routing: After a visit, the AI gauges satisfaction from survey responses and appointment notes. Happy patients receive review requests. Unhappy patients receive recovery outreach. Klaviyo sends the same email to both.
These triggers require a platform that natively understands service-business data — not an e-commerce engine retrofitted with workarounds.
