The question that decides it

Do you send for clients? Smartlead lets an agency keep each client in a separate workspace, from its Pro plan, and brand it as its own for $29 a month per client. Instantly’s pricing page doesn’t list client workspaces.

If you send for your own business, the two are close. Both include unlimited email accounts and warm-up on every plan. Then the price at your volume decides it, so try the calculator below.
