Which plan to pickRun 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.There is one main plan, priced by your spend. Use the 7-day trial on a small part of your budget, check the price shown in the app for your spend level, and only add Tracking Pro if your Meta numbers clearly undercount sales.
