Why does it matter for agencies?
ScaledMail turns cold email infrastructure from an agency time sink into a line-item cost: Google Workspace mailboxes at $3.5 monthly, SMTP at $3.75, and Microsoft Outlook at $50, each with SPF, DKIM, and DMARC configured. Because setup, warmup, and deliverability management sit with the vendor across Smartlead, Instantly, Apollo, and 9 other sequencers, delivery teams stop absorbing onboarding hours per client. The strategic stake is margin per retainer: agencies that keep inbox setup in-house pay for it in senior hours, while agencies that outsource it to ScaledMail price the same retainer against a predictable per-mailbox cost.
