Pros & Cons of Klaviyo
What it gets right

- • Support is slow on lower tiers

The Pricing Trap: How Klaviyo Scales
"Klaviyo penalizes you for growing your list. Expanding from 10k to 50k subscribers increases your bill exponentially, even if those users rarely buy."
Architectural Verdict
While Klaviyo penalizes your growth by exponentially increasing your monthly bill as your subscriber list expands, Systeme.io / Brevo allows you to scale indefinitely with flat-rate or significantly cheaper volume pricing, saving massive margin at scale.
How to migrate to Systeme.io / Brevo
Migrating away from Klaviyo requires following this exact architectural path to prevent data loss and ensure a seamless cutover:
- Step 1: Export all historical data (CSV/JSON) directly from the Klaviyo admin dashboard before canceling your subscription to prevent data loss.
- Step 2: Install and configure Systeme.io / Brevo, using our free blueprint to map your existing data structures to the new system.
- Step 3: Run both systems in parallel for a 7-day testing phase to verify data parity, then officially uninstall Klaviyo from your Shopify store.
