In short

How much does mailfloss cost?

mailfloss is priced by how many contacts you verify, not by seats. Subscriptions run automated cleanup continuously across your connected email platform, while prepaid credits cover one-off bulk CSV checks with no subscription. A free trial lets you clean your list before you pay, and plans scale up as your list grows — so you only pay for the verification volume you actually use.
