What each one counts as a billable contact

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.

Mailchimp. Mailchimp's contact table publishes a yes or no per status. Subscribed, unsubscribed and non subscribed contacts all count toward the monthly contact limit. Cleaned contacts, which is where hard bounces land, do not. Pending contacts do not count and are deleted after 60 days if they never confirm. Unsubscribed contacts stay on the bill until they are archived.

Omnisend stays on the watchlist. This page compares its recorded cells with Mailchimp. It does not insert Omnisend into the six vendor matrices. Omnisend has its own pricing page, and Mailchimp has the full ladder.
