# Agent guardrails that actually work for email

*@helena_p | Agentic Email | 1 year ago*

Genuine question for the forum. Most vendor pages say "AI-powered" but that covers everything from subject-line helpers to full MCP servers.

Specifically interested in automations and automation depth.

**carlos_m** (55 votes): We tried this last quarter. Read-only MCP first made the difference.

  **samira_p** (32 votes): Seed-list before full send. Non-negotiable for agent-triggered mail.

    **sendgrid_legacy** (82 votes): Have you capped daily sends? We hit a loop once and reputation dipped.
