Accepted Answer

Outlook 365 inboxes start at $0.35/inbox (standard) and $0.50/inbox (pre-warmed). Google Workspace inboxes start at $3/inbox (standard) and $4.50/inbox (pre-warmed). All plans include SPF, DKIM, and DMARC configuration.

All inboxes are delivered within 24-72 hours, fully configured with DNS authentication records and ready to connect to your cold email sending platform.

Question 4

What is a pre-warmed inbox?

Accepted Answer

A pre-warmed inbox has already completed the email warmup process, establishing sending reputation with Gmail and Outlook servers. This means you can start sending cold emails immediately without the typical 2-3 week warmup period.

Do I need to set up DNS records myself?

Accepted Answer

No. Puzzle Inbox handles all DNS configuration automatically, including SPF, DKIM, DMARC, and MX records. Every inbox is delivered fully configured and verified.
