Cold email that lands, from infrastructure you own.
Warm up your domains, rotate your mailboxes, and pace every sequence so your mail keeps landing.
Warmup gates volume
A new mailbox starts small and only earns a higher daily cap once its warmup mail keeps landing.
Graded per sender
Bounce and complaint rates are tracked by campaign, mailbox, and domain, so a degrading sender is named before it spreads.
Suppression enforced
Unsubscribed and bounced addresses are skipped before a send leaves the queue.
