"Hey everyone! We built Puzzle Inbox because scaling cold email infrastructure was way harder than it needed to be. Buying domains, setting up DNS records, warming inboxes, it's tedious work that pulls sales teams away from actually selling. Puzzle Inbox handles all of it. You get pre-warmed Google Workspace or Outlook 365 inboxes with SPF, DKIM, and DMARC configured automatically, delivered in 24-72 hours. Outlook inboxes start at $0.35 and Google Workspace at $3. We've now deployed over 70,800 inboxes for 1,200+ agencies and sales teams, and we're rated 4.7/5 by our clients. Would love to hear your feedback, happy to answer any questions about cold email deliverability or how we handle the setup process!"
