What to test before upgrading
Use the same small ecommerce list in your evaluation criteria: build a signup form, welcome automation, abandoned-cart flow and one promotional campaign. Compare setup time, segmentation, reporting, integration quality and how each platform counts contacts or active profiles before moving your full customer database.
Do equal free limits mean the products cost the same later?
No. The current free limits happen to be similar, but paid billing rules differ. Omnisend publishes Standard and Pro starting prices and adjusts tiers with billable contacts. Klaviyo's paid price depends on your active profile count and selected messaging products. Estimate the paid bill using each vendor's live calculator before choosing based on free limits alone.
