How to decide whether to continue transactional emails?

Continue transactional if:

• Separate IP from marketing
• Separate subdomain with isolated reputation
• Transactional metrics remain healthy
• Business-critical (passwords, receipts, confirmations)

Stop or limit transactional if:

• Shares infrastructure with affected marketing
• Transactional also showing problems
• Blocklist affects all sending

Mitigation options:

• Throttle volume if continuing
• Monitor closely for contamination
• Have backup sending path ready

Transactional streams are high-value and high-engagement. Protect them from marketing reputation problems.

Essential cargo may still ship if using clean vessels and routes.
