Nestlé recovered €5 million in email-attributed revenue after a deliverability crisis that had suppressed inbox placement across multiple markets. Data Innovation, led by Florin Armasu, built and deployed a new dedicated IP architecture using the VDMS (Volume Delivery Management System), completed a full authentication audit, and ran coordinated IP warming campaigns across multiple MTAs. The result: reliable inbox placement restored at scale, with commercial programs back to full revenue capacity.
Challenge
Nestlé sends at very large email volumes across multiple geographies and business units. When inbox placement rates dropped, the commercial impact was direct and measurable: promotional campaigns reached fewer customers, revenue from email-driven offers fell, and the brand’s sender reputation began to accumulate damage that compounds over time if left unaddressed.
The core problem was a combination of authentication gaps and IP infrastructure that had not scaled correctly with sending volume. Without clear DMARC enforcement, domain abuse went undetected. Without dedicated IP architecture calibrated to actual sending patterns, mailbox providers had no consistent signal to trust the sender identity.
The situation required a structured recovery, not a tactical patch. Rebuilding sender reputation at Nestlé’s volume means executing IP warming with precision, because any warmup error at high volume sets the process back weeks.
Approach
Data Innovation applied the VDMS (Volume Delivery Management System) framework, which treats email deliverability as an infrastructure and governance problem rather than a content problem.
The first step was a full authentication audit across all sending domains. DMARC, DKIM, and SPF configurations were reviewed, corrected, and moved to enforcement mode with DMARC reporting activated. This gave Nestlé visibility into unauthorized sending activity and gave mailbox providers a verified identity signal.
The second step was rebuilding the IP architecture. Dedicated IP pools were assigned by sending program type (transactional, promotional, reactivation), separating traffic streams that previously shared reputation. Each pool was sized to the volume of its program, avoiding underuse that signals inactive IPs.
The third step was IP warming. Across multiple MTAs, warming schedules were built per domain, per ISP, and per IP pool. Volume was ramped gradually, with engagement metrics monitored daily to catch any ISP-specific anomalies before they became blocks. Florin Armasu, an IESE Research Fellow with deep experience in email infrastructure, led the technical execution.
Throughout the project, Data Innovation monitored bounce codes, feedback loop signals, and seed network inbox placement to confirm that reputation was building, not degrading.
Results
Following the VDMS implementation and IP warming:
- €5 million in email revenue was restored as inbox placement rates recovered across key markets.
- DMARC enforcement eliminated unauthorized domain use, protecting brand integrity.
- The new IP architecture gave Nestlé a foundation for sustained deliverability at their required sending scale.
- The sending infrastructure was documented and handed over to Nestlé’s internal team with operational runbooks for ongoing management.
Email deliverability at enterprise volume requires the same rigor applied to any critical infrastructure: clear ownership, correct configuration, and a systematic approach to change. The Nestlé engagement demonstrates that even after a serious reputation event, recovery is achievable with the right architecture and execution discipline.
