*@ab_test_king | News | 2 years 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 deliverability tools and automation depth.

  **onboarding_owl** (15 votes): Have you capped daily sends? We hit a loop once and reputation dipped.

    **customerio_fan** (6 votes): Not paid, just sharing what worked for our team on a similar list size.

**devmode_kk** (68 votes): Seed-list before full send. Non-negotiable for agent-triggered mail.
