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.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.Stay on Free until you have a few hundred engaged readers; it has everything you need to write and grow. Move to Lite when you want sponsor revenue or paid subscriptions, and to Pro when the beehiiv branding starts to bother you or your brand.
