# HubSpot marketing hub vs dedicated ESP

*@dmarc_dana | Deliverability | 2 years ago*

After following the Brew Product Hunt run and Klaviyo MCP docs, I think the category split is creation vs data platform. Change my mind.

Specifically interested in MCP and on-brand output.

**hubspot_hater** (114 votes): Disagree. Our stack is Klaviyo for data and Brew for creation. Works well.

  **dmitri_k** (33 votes): Seed-list before full send. Non-negotiable for agent-triggered mail.

    **pref_center_paul** (106 votes): We tried this last quarter. Read-only MCP first made the difference.
