Protect Your Sending Reputation — Register and age backup domains before you need them. Plan Ahead →

When should you register new domains?

Proactive domain registration prevents scrambling when domains need replacement.

Proactive registration:

  • Register backup domains before you need them
  • Allow 4 to 8 weeks of aging before warmup
  • Maintain inventory of domains at different stages
  • Budget for domain rotation as operational cost

Triggers for new domain registration:

  • Current domain showing reputation problems
  • Approaching scale limits on existing domains
  • Planning significant volume increases
  • Entering new markets or segments
  • Current domains approaching fatigue

Domain inventory strategy:

  • Active domains: Currently sending campaigns
  • Warming domains: In warmup phase, nearly ready
  • Aging domains: Registered, DNS configured, resting
  • Reserve domains: Purchased, minimal setup, emergency backup

Registration best practices:

  • Choose domains related to your brand for recognition
  • Avoid patterns that look like domain spinning
  • Set up basic DNS immediately (A record, MX, authentication)
  • Create minimal web presence
  • Purchase for multiple years (longevity signal)
