Timeline: 7-10 days initial outreach, 21-28 days with follow-ups

Standard setup for most businesses

Optimizing Campaign Speed

To speed up your campaigns while maintaining deliverability:

  • Add more mailboxes: More accounts = higher daily capacity
  • Reduce delays carefully: Balance speed with deliverability
  • Use warmed accounts: Established accounts have higher limits
