Which plan to pickStart on Free to see if you will actually post regularly. Move to Essentials once you need more than 10 posts queued per channel; Team is only worth it when someone else needs to approve posts.Start on Free and stay there while you're only sending a newsletter. Move to Creator once you want a welcome sequence or automations, which is usually the moment a list starts making money. Prices rise with subscriber count, and Kit often runs first-year discounts on Pro.Most small businesses should take the hosted Team plan for the team access and AI images. Standard works for a solo creator. Self-host only if you or someone on your team is comfortable running a server.
