ActiveCampaign vs MailerLite for AI agents

As of 6 Oct 2026, both reach L1 · Needs a person, and with each our agent was stopped at sign up (needs a human).

Stopped at sign up: needs a human. Next: let an agent sign up on its own

Needs a person: our agent reached the trial form but could not sign up on its own. A Cloudflare managed challenge, a visible Turnstile check, stopped it at signup, and the vendor's own agent guidance says accounts cannot be created or trials started this way. With no account, our agent never reached verification or the Settings page where a token or MCP URL is issued, so no call and no work through the API, CLI or MCP server. Docs are agent-ready: llms.txt, markdown pages, OpenAPI specs and a docs MCP all worked. Paying needs a human past that same challenge first, and there is no delete-account API.

Stopped at sign up: needs a human. Next: let an agent sign up on its own

Needs a person to get in, at L1 · Needs a person. Sign-up stops first: the form sits behind a visible Cloudflare Turnstile check, so our agent couldn't create an account. Verification, the API token page, OAuth login for CLI and MCP, the first call, paying and cancelling all read not reached for that reason. MailerLite ships Markdown docs with llms.txt, an official CLI, SDKs and a hosted MCP server, but none of it gets driven: the product stays locked behind that one form until a person clears the check and makes the key.

A check of our network and browser: It judged where our agent connects from and its browser, not a person. An agent that works on its own from a data center doesn't get through unless the owner lets signed agents in. How agents in a person's own browser fare isn't measured yet. Where we drive from.
