ScaledMail Multi-Client Inbox Infrastructure Build (7-10 days)

A repeatable build that turns ScaledMail's managed Google, Microsoft 365, and SMTP inbox provisioning into a billable infrastructure retainer, so agency delivery teams hand clients warmed, DNS-verified sending domains instead of a setup backlog.

Prerequisites
  • Client domains registered at any registrar, with registrar access available for DNS record changes
  • Confirmed monthly sending volume and target mailbox count per client, since ScaledMail pricing scales with mailboxes and domains
  • Client's sequencing platform identified from ScaledMail's supported integrations (Smartlead, Instantly, Apollo, EmailBison)
  • Agency Slack channel or shared workspace for ScaledMail's dedicated support access
  • Signed scope that separates infrastructure fees from copy and targeting work
Execution Timeline
  • 1.Audit the client's current cold email setup and confirm ScaledMail fits: managed inbox setup, pre-warmed inboxes, and sequencer compatibility
  • 2.Map required sending volume to a provider mix across Google Workspace, Microsoft 365, and SMTP, noting ScaledMail's mailbox-per-domain limits
  • 1.Collect domains from the client's registrar and decide how many domains are needed to stay inside the 2 to 3 mailbox Google Workspace limit per domain
  • 2.Draft the infrastructure line item on the client proposal using ScaledMail's published per-mailbox rates
  • 1.Provision the first Google Workspace mailboxes through ScaledMail at $3.5 monthly per mailbox, capped at 25 emails per mailbox per day
  • 2.Confirm SPF, DKIM, and DMARC records are configured by ScaledMail before any send
  • 1.Stand up Microsoft Outlook mailboxes at $50 monthly per domain for the 25-mailbox, 10-emails-per-day tier where the client needs volume
  • 2.Add SMTP Server mailboxes at $3.75 monthly for the 4-mailbox, 10-emails-per-day tier as a lower-cost sending lane
  • 1.Connect each provisioned inbox to the client's sequencer (Smartlead, Instantly, Apollo, or EmailBison) and verify send/receive on a test sequence
  • 2.Set the inbox warmup schedule and record baseline deliverability scores
  • 1.Load the client's first cold outreach sequence into the connected sending tool and route it through the ScaledMail inboxes
  • 2.Document mailbox-to-domain mapping so the agency team can rotate senders without re-provisioning
  • 1.Run a 48-hour deliverability watch: bounce rate, spam placement, and per-mailbox send caps
  • 2.Escalate anomalies through ScaledMail's dedicated Slack support with cold email specialists
  • 1.Package the build into a client-facing handover: inbox inventory, DNS record summary, warmup status, and monthly send ceiling
  • 2.Set the agency's monthly monitoring cadence and define what triggers a new domain purchase
  • 1.Reconcile actual mailbox count against the quoted infrastructure fee and adjust the retainer line before invoicing
  • 2.Log the build as a reusable template for the next client onboarding
$3.5 per Google Workspace mailbox monthly, $50 per Microsoft Outlook domain monthly, and $3.75 per SMTP mailbox monthly; a typical 10-mailbox single-domain client build lands near $35 to $85 monthly in ScaledMail fees before agency markup7-10 days
ROI Logic

ScaledMail's per-mailbox rates are small enough that a 10-mailbox Google Workspace build costs roughly $35 monthly, while the agency bills infrastructure setup and monitoring as a separate retainer line. The margin comes from charging for the DNS, warmup, and sequencer wiring work once and reusing the template across every new client, not from marking up the mailbox fee. Microsoft Outlook at $50 monthly per domain only makes sense when a client genuinely needs 25 mailboxes, so scope discipline protects the retainer's gross margin.

Deliverables
  • Inbox inventory sheet mapping every ScaledMail mailbox to its domain, provider, and daily send cap
  • DNS verification record showing SPF, DKIM, and DMARC configured per sending domain
  • Sequencer connection log confirming each inbox is live in Smartlead, Instantly, Apollo, or EmailBison
  • Warmup and deliverability baseline report with 30-day ramp tracking
  • Client handover document with monthly send ceiling and domain expansion triggers
Definition of Done

Every ScaledMail-provisioned inbox is DNS-verified, connected to the client's sequencer, and sending inside its daily cap with a documented warmup baseline the agency can monitor monthly.
