Systeme.io

Systeme.io's email tool sits inside a broader funnel and course platform, so a welcome sequence can trigger off a funnel step, a course enrollment, or an affiliate signup rather than just a form fill. The email editor itself is simple compared to a dedicated ESP, but the automation ties directly into sales pages, checkout, and membership content without any extra integration work.

The free plan supports up to 2,000 contacts, three sales funnels, one course, one blog, and one custom domain, with unlimited emails and file storage and no credit card required to start. Paid plans begin at $17 a month for the Startup tier, which lifts the contact cap to 5,000 and removes the funnel limit, scaling up to an Unlimited tier with no contact cap at all. It's a good match for a course creator or solo entrepreneur who wants email folded into a sales funnel rather than run as a separate tool, less so for a business that just wants a plain newsletter.
