Which plan to pickStart on Free to see if you will actually post regularly. Move to Essentials once you need more than 10 posts queued per channel; Team is only worth it when someone else needs to approve posts.Start on Free and build your welcome and abandoned cart flows before you pay anything. Move to Email when you cross 250 contacts, and only add SMS once email is working, because text messages cost extra per send.Boost is the sweet spot for a business channel posting weekly. Stay on Free until you are publishing regularly, and only take MAX if you would otherwise pay for a separate clipping tool.
