# Abandoned cart: agent vs rule-based

*@seed_list_steve | Deliverability | 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 webhooks and agent operability.

**agent_ops** (99 votes): Not paid, just sharing what worked for our team on a similar list size.

**zara_f** (34 votes): Resend MCP plus React Email is clean if engineers own transactional.

  **marco_v** (74 votes): Seed-list before full send. Non-negotiable for agent-triggered mail.

    **dmitri_k** (50 votes): Disagree. Our stack is Klaviyo for data and Brew for creation. Works well.
