# Preference centers and consent sync

*@aisha_r | B2B SaaS | 4 months ago*

Context: enterprise lifecycle team, 250k monthly sends. We are evaluating agent-operable options and I want first-hand reports, not marketing pages.

Specifically interested in deliverability tools and API quality.

## Comments

**flow_builder** (63 votes): Seed-list before full send. Non-negotiable for agent-triggered mail.

  **fatima_h** (105 votes): Resend MCP plus React Email is clean if engineers own transactional.

**resend_reviewer** (24 votes): OAuth setup took an afternoon but tool discovery is worth it.

**ingrid_s** (12 votes): Have you capped daily sends? We hit a loop once and reputation dipped.

  **copy_test_a** (75 votes): Resend MCP plus React Email is clean if engineers own transactional.

    **seed_list_steve** (94 votes): We tried this last quarter. Read-only MCP first made the difference.
