Nick of CoreConversions talks through why the agency runs its cold email on WarmInboxes prewarmed inboxes.

Nick runs CoreConversions, an agency sending cold email on behalf of its clients. In this review he covers what prewarmed infrastructure changes about the first week of a campaign, when the alternative is sitting through a warmup before a single prospect hears from you.

Agency work is the case prewarmed inboxes were built for: a client signs, and the outreach is expected to start, not to start in three weeks. Inboxes that arrive configured and already warmed take the warmup window out of the onboarding entirely.
