Private email infrastructure & deliverability engineering
Industry

Performance Agencies

Media buyers and performance agencies operate under client-brand attribution but need infrastructure they control. Northbound provides an upstream that agencies can white-label or attribute openly, with per-client isolation.

Challenges

  • Client onboarding cadence is fast; provisioning must match
  • Per-client IP isolation prevents one client's list issues from harming another's
  • Reporting expectations vary widely across clients
  • Attribution — agency vs. client on WHOIS, DNS and DMARC — needs to be decided per engagement

Our approach

  • Per-client IP allocation with fast provisioning cycles
  • White-label option: agency-branded WHOIS, nameservers and support routing
  • Per-client reporting templates aligned to the agency's client review cadence
  • Direct engineer access to the agency's ops team, not to end clients

Deliverability recommendations

  1. Standardise domain topology across clients to reduce operational surface
  2. Enforce per-client DMARC posture even if the client is not asking for it
  3. Route abuse and unsubscribe to a per-client mailbox

Example engagements

  • European performance agency: onboarded 14 client programmes onto per-client IP allocations over eight months; retained deliverability engineer embedded weekly.

Examples are anonymised. Named references available under mutual NDA.

Questions

Can we resell your infrastructure to our clients?
As part of an agency retainer, yes. We do not do standalone wholesale/reseller relationships outside that model — see our SMTP resellers page for that.
