Which plan to pickStart 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.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.Start on Free and use it until the lack of attribution actually costs you a decision. Foundation is the plan most brands need, but it is quoted on your revenue and locks you in for a year, so ask for the full price table before you commit.
