Puzzle Inbox handles the infrastructure side of cold email so teams can focus on selling instead of configuring DNS records. They set up domains, configure SPF, DKIM, and DMARC, provision Google Workspace or Outlook 365 accounts, and manage the warmup process end to end. Every inbox is delivered fully authenticated and ready to connect to a sending tool within 24 to 72 hours. Pre-warmed options let clients start sending real campaigns on day one without waiting weeks for reputation to build. Outlook starts at $0.35/inbox and Google Workspace at $3. Over 1200 teams trust them with more than 70000 active inboxes deployed.
