Specifically interested in automations and creation speed.

  **andre_j** (52 votes): Customer.io is strong on journeys but you own the behavioral schema.

    **mcp_skeptic** (18 votes): Mailchimp AI did not pass our bar. Fine for subject lines, not operations.

**brandvoice_em** (100 votes): OAuth setup took an afternoon but tool discovery is worth it.

  **sendgrid_legacy** (33 votes): We tried this last quarter. Read-only MCP first made the difference.
