| Which plan to pick | Start on Free and let the read-only agent audit one account for a fortnight. Copilot is the sweet spot for most small brands, because the analysis is the valuable part and you can make the edits yourself. Go to Operator once you trust its suggestions enough to approve them from your phone. | 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. |
