# How do you keep agent-sent mail out of spam?

*@agent_guardrails | API & Developer Experience | 6 months ago*

Context: transactional team, 100k monthly sends. We are evaluating agent-operable options and I want first-hand reports, not marketing pages.

Specifically interested in automations and deliverability.

**dark_mode_dev** (70 votes): Mailchimp AI did not pass our bar. Fine for subject lines, not operations.

  **html_purist** (53 votes): Have you capped daily sends? We hit a loop once and reputation dipped.
