What Coldoutbound does, what it doesn't, and what costs money.

• Mailboxes: send cold email from the addresses you already ownConnect Gmail, Microsoft 365 or any SMTP mailbox. Coldoutbound sends through your own accounts at a slow pace and reads the replies. No charge per mailbox.
• Warm-up ramp: why a new mailbox starts at 3 emails a dayWhy a new mailbox has to start slowly, why Coldoutbound's warm-up ramp goes 3, 6, 9 up to 20, and what happens when a receiving server pushes back.
