“We deploy it for every ecommerce client now”
Used daily for 2+ years
Across about a dozen client accounts, Klaviyo consistently produces better revenue per send than whatever they arrived on. The setup work is front-loaded but the templates make it repeatable.
Pros
Consistent results, deep Shopify integration, strong documentation.
Cons
Not worth it for clients under roughly $20k monthly revenue — the cost outweighs the lift.
