Neither vendor is in the six vendor comparison tables on this site. Moving either into those tables would need a free plan record, a contact counting record, and a changelog entry, and it would move the vendor count that several titles carry. Omnisend has its own pricing page, and Klaviyo has a change record and a pricing page with every Email stop.

Omnisend. Opted in to marketing on email, SMS or push. The number most people mean when they say list size. Placed an order, abandoned a cart, created an account or arrived in an import without a marketing consent box. They never opted in and they are still billed, because Omnisend can still send them transactional and automated messages. Opted out after consenting. Omnisend states on the pricing page and on four help pages that unsubscribers are not charged for, and it advises unsubscribing inactive contacts rather than deleting them so the purchase history survives.

Klaviyo. An active profile is anyone the account is allowed to email, including never subscribed contacts. Suppressed profiles stay out of the count. A list built over years now bills whether it is mailed or not. The February 2025 change moved older accounts onto that rule as well, with a 25 percent increase cap rather than a grace period. That sequence is recorded here.

Put one store list through both rules and the gap stops being theoretical. A store with 8,000 subscribers, 3,000 customers who never opted in, and 1,000 unsubscribers is billed near 11,000 contacts on Omnisend and near 11,000 active profiles on Klaviyo if the never subscribed contacts are still emailable. Unsubscribers leave the Omnisend billable count and leave the Klaviyo count only when suppressed. Same store, and the tier each platform picks can still diverge once suppression and non subscriber rules are applied carefully.

Omnisend Standard includes 12 times the billable contact count in monthly email credits. At 10,000 contacts that is 120,000 emails for $132 a month. Pro removes the email cap.

Klaviyo Email carries roughly 10 times the profile count in monthly sends. At 10,000 profiles that is 100,000 emails for $150 a month. Passing the allowance is a separate problem from the profile tier, and neither problem is solved by reading only the sticker price.
