Setting up outreach mailboxes

Buy a sending domain and mailboxes hosted by Overjoy, let them warm up, and get them ready for cold outreach.

Key takeaways

  • Use a separate domain for cold outreach to protect the reputation of your main business domain.
  • Buy a domain under Settings → Domains → Buy Domain, then create two or three mailboxes with a sender name and address buyers will recognize.
  • Allow about fourteen days of warmup before sending campaigns or automations from the new mailboxes.
