ConvertKit's core is the same buildable email-and-list pattern as Mailchimp, just positioned for creators instead of businesses. The visual automation builder (if a subscriber does X, wait, then do Y) is the part that takes real work to match.

Two real costs, not just "free": the AI agent's own usage, and hosting once it's running. Both are estimated from this app's own effort rating and component list — see the assumptions on the method page.
| AI agent — with a subscription (Claude Pro/Max, Cursor, etc.) | $0 marginal |
| AI agent — pay-per-use API, no subscription | $43–$86 one-time |
| Hosting, once it's running | $0/mo (free tier) |
| Domain name, if you want your own | ~$12/yr |
ConvertKit costs $25/mo. Even paying per-token with no subscription, and accounting for hosting, this build pays for itself in about 4 months.
