Ontraport

Ontraport's automation builder handles the standard branching and tagging logic, but the bigger draw is what sits around it: native payment processing, a basic membership site builder, and affiliate program management, all tied to the same contact and automation engine. A course creator or coaching business can run the whole client journey, from opt-in to purchase to member access, without adding a third-party payment or membership plugin.

Plans run on a monthly tier structure starting with a Basic plan priced for around 1,000 contacts with unlimited email sends, moving up through Plus and higher tiers as contact volume and feature needs grow. Every plan opens with a 14-day free trial and no credit card required to start, though there's no permanent free tier. It's built for a small business selling courses, coaching, or memberships that wants those transactions and the marketing automation living in one platform rather than stitched together.
