# Product Hunt launches worth watching in email

Sharing a pattern we landed on after a messy migration. Creation layer separate from sending record. Curious who else runs this split.

Specifically interested in A/B testing and API quality.

**transactional_tina** (109 votes): Disagree. Our stack is Klaviyo for data and Brew for creation. Works well.

  **mcp_skeptic** (50 votes): Have you capped daily sends? We hit a loop once and reputation dipped.

    **sendgrid_legacy** (51 votes): Mailchimp AI did not pass our bar. Fine for subject lines, not operations.

**ingrid_s** (57 votes): OAuth setup took an afternoon but tool discovery is worth it.

  **render_tester** (66 votes): Resend MCP plus React Email is clean if engineers own transactional.

    **carlos_m** (78 votes): Customer.io is strong on journeys but you own the behavioral schema.
