| Which plan to pick | Platinum covers research for most sellers getting started. Move to Diamond once ads and listing work take up real time each week, because that is where the automation lives. | Run the free CRM for as long as you can; it covers most small businesses. Starter is the sensible first paid step when you want the branding gone and more sends. Only move to Professional when you have a specific automation in mind that will pay for the jump. | 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. |
