| Which plan to pick | Plus is the sweet spot for most small businesses because it adds landing pages and generative AI. Starter is fine if you only need simple automations. Prices on ActiveCampaign's own page load per contact count, so plug in your real list size before deciding. | Start 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 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. |
