What Warmup Inbox is
Warmup Inbox builds sender reputation by exchanging real conversations across a network the vendor puts at more than thirty thousand inboxes, reports where test messages land, and works to get a domain off blacklists. It does one thing and is priced per mailbox warmed, which makes it worth comparing directly against the sending platforms that include warm-up in the subscription.
