Specifically interested in deliverability tools and automation depth.

**ai_skeptic_2024** (10 votes): Not paid, just sharing what worked for our team on a similar list size.

  **dmitri_k** (72 votes): Have you capped daily sends? We hit a loop once and reputation dipped.

    **stack_migrator** (54 votes): Disagree. Our stack is Klaviyo for data and Brew for creation. Works well.

**split_stack_advocate** (45 votes): Resend MCP plus React Email is clean if engineers own transactional.
