Executive Decision Framework

When to Choose Managed ESPs

  • Volume < 1M emails/month

  • Need built-in compliance and security

  • Want predictable costs and support

When to Consider Self-Hosted

  • Volume > 10M emails/month

  • Have 4-6+ email infrastructure engineers

  • Email is core product (not just marketing)

  • Need complete infrastructure control

  • Have complex custom requirements
