# Email account management

Managing multiple email accounts is essential for scaling cold email operations while maintaining deliverability. Proper account management includes rotation strategies, health monitoring, and operational best practices that protect your infrastructure and ensure consistent performance. This lesson covers how to effectively manage email accounts for cold email.

Key Takeaways
- Account rotation spreads risk and maintains deliverability

* - Monitor each account's health individually * - Have backup accounts ready for emergencies * - Follow provider limits and terms of service

Account strategy

Account types

Primary accounts:

  • Main sending accounts
  • Higher volume capacity
  • Established reputation
  • Critical infrastructure

Secondary accounts:

  • Backup sending capacity
  • Testing and experimentation
  • Volume overflow handling
  • Emergency fallback

Burner accounts:

  • Short-term campaigns
  • High-risk outreach
  • Temporary projects
  • Disposable infrastructure

Account distribution

Per domain strategy:

  • Low volume: 1-2 accounts per domain
  • Medium volume: 3-5 accounts per domain
  • High volume: 5-10 accounts per domain
  • Enterprise: Dedicated infrastructure

Multi-domain strategy:

  • Distribute accounts across multiple domains
  • Isolate reputation risks
  • Provide backup capacity
  • Enable domain rotation

Account rotation

Rotation principles

Load balancing:

  • Distribute volume evenly across accounts
  • Prevent any single account from overuse
  • Maintain consistent sending patterns
  • Respect individual account limits

Risk spreading:

  • Don't rely on single points of failure
  • Isolate reputation issues
  • Enable quick recovery
  • Maintain operational continuity

Rotation methods

Round-robin rotation:

  • Cycle through accounts sequentially
  • Equal distribution of volume
  • Simple to implement
  • Predictable patterns

Weighted rotation:

  • Prioritize healthy accounts
  • Reduce usage of struggling accounts
  • Dynamic adjustment based on performance
  • Optimized for deliverability

Random rotation:

  • Random account selection
  • Unpredictable patterns
  • Natural distribution
  • Harder to detect

Rotation implementation

Manual rotation:

  • Spreadsheet tracking
  • Manual account selection
  • Regular review and adjustment
  • Suitable for small scale

Automated rotation:

  • Tool-based distribution
  • Automatic load balancing
  • Performance-based adjustment
  • Scalable for high volume

Health monitoring
