Outbound Infrastructure and Deliverability Retainer Build (14-21 days)
A productized engagement that stands up sending domains, mailbox rotation, warmup, and reply-handling rules for a client's outbound program, then hands over a monitored retainer. It sells the operating layer around cold email rather than access to any single sending tool.
- Signed scope covering domain and mailbox ownership, since the client must retain registrar and DNS control at handover. Written audience hypothesis naming the segment, the trigger event, and the disqualifiers. Confirmed sending volume ceiling per domain per day, agreed with the client before any inbox is connected. Named client-side approver for message copy and for the qualification rules that decide which replies become meetings. Documented jurisdiction and consent position for every country the client intends to contact.
- 1.Inventory the client's current sending domains, mailboxes, and DNS records
- 2.Record baseline bounce, spam complaint, and reply rates from the last 60 days
- 3.Confirm the audience hypothesis and the disqualification list in writing
- 1.Register secondary domains and set SPF, DKIM, and DMARC records
- 2.Map mailbox count to the agreed daily volume ceiling
- 3.Document the domain-to-client ownership handover path
- 1.Connect mailboxes to the chosen platform and verify send permissions
- 2.Start warmup on every new mailbox with a fixed ramp schedule
- 3.Log the ramp schedule so the client can see when full volume begins
- 1.Build the list from the approved sources and run verification
- 2.Suppress existing customers, open opportunities, and prior opt-outs
- 3.Freeze the list and record its provenance for the compliance file
- 1.Draft the first sequence: opening message, two follow-ups, one breakup note
- 2.Write the qualification rules that route replies to meeting, nurture, or discard
- 3.Send copy to the client approver and log the approval version
- 1.Configure reply detection and the routing rules in the automation stack
- 2.Set the daily send cap per mailbox and the rotation order
- 3.Test the full path with internal seed addresses
- 1.Launch a 200-contact pilot batch from one domain
- 2.Monitor inbox placement, bounce rate, and first replies for 48 hours
- 3.Hold the remaining volume until the pilot clears the placement threshold
- 1.Review pilot metrics against the baseline recorded on day 1
- 2.Rewrite any message with a reply rate below the agreed floor
- 3.Expand to the full mailbox set if placement holds
- 1.Publish the weekly deliverability report template with the five tracked metrics
- 2.Set the domain burn alert threshold and the pause rule
- 3.Confirm who on the client side receives the alert
- 1.Run a compliance review of list provenance, opt-out handling, and jurisdiction coverage
- 2.Capture a sample of agent or automation outputs and compare against the approved scope
- 3.Log any deviation in a versioned change record
- 1.Hand over domain credentials, DNS access, and the runbook
- 2.Walk the client team through the retainer monitoring cadence
- 3.Agree the monthly review date and the meeting target attached to it
The build phase is priced on infrastructure work, not on tool access, because the client can buy seats anywhere but cannot easily buy a working sending setup. The retainer is defensible because deliverability decays without weekly attention: domain reputation, list hygiene, and reply routing all drift once volume scales. Agencies that attach meeting targets to the retainer should price the monitoring hours separately so a bad month does not turn into unpaid remediation work.
- Domain and mailbox architecture document with DNS records and ownership notes
- Warmup and rotation schedule tied to the agreed daily volume ceiling
- Sequence copy set with the client approval record and version history
- Qualification and reply-routing rules, including the discard criteria
- Weekly deliverability report template with alert thresholds and pause rules
The client's domains send at the agreed daily volume with inbox placement above the threshold set on day 1, reply routing is live, and the client holds credentials plus a signed runbook for the monitoring retainer.
