Puzzle Inbox is a cold email infrastructure provider offering pre-warmed Google Workspace and Outlook 365 inboxes, fully configured and ready to send in 24โ€“72 hours.

Setting up cold email inboxes from scratch is time-consuming and risky. Poor inbox warming leads to emails landing in spam, killing deliverability and wasting outreach budgets.

Every inbox comes with complete DNS setup handled automatically โ€” including SPF, DKIM, DMARC, and OAuth configuration. No technical knowledge required. No back and forth with IT. Just inboxes that are configured correctly and built to land in the primary inbox, not spam.

For teams who want to go further, Puzzle Inbox offers a fully managed done-for-you cold email service. From inbox setup and warming through to copywriting, sending, and campaign management โ€” everything is handled so your team can focus on closing deals, not managing infrastructure.

Whether you're an outbound sales team, a lead generation agency, or a SaaS company looking to grow pipeline, Puzzle Inbox gives you the infrastructure to scale quickly and reliably. Order inboxes, connect to your cold email tool via SMTP or IMAP, and start sending โ€” all within 24โ€“72 hours.
