the problem

Infrastructure shouldn't kill your campaigns.

Most outreach teams lose time to email infrastructure. Scaling cold email shouldn't be this hard, so we built Diamond Mail to handle it.

common problems include
  • Poorly configured DNS records
  • Cheap inbox providers getting flagged
  • Burned domains and low deliverability
  • Paying $7–$8 per inbox on Google Workspace
  • Spending hours setting up accounts
