Pre-warmed mailboxes with real sending history
Skip the 14–21 day ramp. Accounts arrive with established reputation — +$2/mo over standard, vs $5 at Icemail and ~$10 at Instantly DFY.
How ours are warmed
An isolated warmup network of real inboxes (not a shared pool of 50,000 senders), human-pattern engagement spread across business hours, and a minimum age of 21 days before any account ships. Transparency here is a differentiator because most providers won't say.
When to choose pre-warmed
Hard deadlines (launch next Monday), replacing burned capacity mid-campaign, or scaling fleet size faster than the standard ramp allows. Patient teams should still start with standard mailboxes and ramp.
Still monitored, still replaceable free
Pre-warmed doesn't mean pre-fragile. Same continuous blacklist scanning, same free unlimited replacement, same isolation as our standard mailboxes.
Instantly DFY ~$10/mailbox · Icemail $5 add-on · CLAYINBOX +$2/mo
