Private email infrastructure & deliverability engineering
Industry

Email Marketing Companies

ESPs and marketing platforms that need serious upstream infrastructure to serve their own customers. Northbound provides the deliverable channel underneath your product.

Challenges

  • Customer sending profiles vary enormously — one platform, many risk profiles
  • Reputation of the upstream affects every customer's outcome
  • Support expectations from your customers become support expectations of us
  • Growth is unpredictable — infrastructure must scale in step

Our approach

  • Per-customer-tier IP pool topology — protect good senders from poor ones
  • Direct engineering channel between your ops team and ours
  • Capacity planning integrated with your growth forecast
  • White-label attribution where required

Deliverability recommendations

  1. Tier customers by reputation and route each tier to appropriate IPs
  2. Enforce your own AUP as strictly as ours; you carry the reputation cost of laxity

Example engagements

  • European marketing platform: consolidated three upstream vendors onto Northbound, per-customer-tier isolation reduced blocklist incidents 84% year-over-year.

Questions

Do you compete with us?
No. Northbound does not operate a marketing UI, does not sell to your customers directly, and does not accept customer referrals from your platform without your consent.
