Works seamlessly with your favourite sequencer
Most teams waste weeks on infrastructure before sending a single email.
Cold email infrastructure is deceptively complex. Between domain reputation, DNS configuration, inbox warming, and sequencer integration — most teams spend more time fighting their tools than actually running campaigns. That's time and money you can't get back.
Spending hours on DNS records, SPF, DKIM, and DMARC setup
Inboxes landing in spam before you even start warming
Shared IP pools destroying your sender reputation
Waiting 4–6 weeks for inboxes to warm up properly
Support tickets that go unanswered for days
Paying premium prices for mediocre deliverability
Everything you need to send at scale — nothing you don't.
ScaledInboxes handles the entire infrastructure stack so your team can focus on what actually drives revenue: great copy, sharp targeting, and compelling offers.
Enterprise-Grade DNS
SPF, DKIM, and DMARC configured correctly from day one. No guessing, no trial-and-error. Your sender reputation is protected by default.
