How Aviloo reached 125,000+ car dealers
across 25 countries with cold email
Aviloo developed the world's first independent, TÜV-certified battery diagnostics system for electric vehicles. They had the technology — they needed a way to reach fragmented buyer segments across dozens of countries and languages. We built the system.

Context
Aviloo is an Austrian technology company that developed AVILOO Battery Test — the world's first independent, TÜV-certified battery diagnostics system for electric vehicles. Their technology gives car dealers, fleet managers, OEMs, and insurance companies an objective health score for EV batteries, solving one of the biggest trust gaps in the used EV market.
The challenge was reach. Aviloo's buyers — car dealer principals, fleet managers, corporate automotive leaders — are spread across fragmented markets worldwide. Reaching tens of thousands of potential buyers across 25+ countries, in 8+ languages, without compromising deliverability or personalization, required a fundamentally different approach to outbound.

The Scale of the Challenge
This wasn't a single-market campaign. Aviloo needed parallel outbound operations across dozens of countries — each with its own language, cultural norms, and buyer expectations. Here's what the system had to support from the start:
Germany, Austria, Switzerland
UK, Ireland, Netherlands, Belgium, France
Italy, Spain, Portugal
Scandinavia, Eastern Europe, and beyond
United States, Canada
Each market required native-quality copy — German, French, Italian, Spanish, Portuguese, Dutch, Flemish, and English. Not translations, but localized messaging that felt authentic to each audience. And each of Aviloo's 10+ SDRs needed their own dedicated sending infrastructure: separate domains, separate inboxes, separate warmup cycles.

Building the Multi-Market Machine
We architected Aviloo's outbound system as a scalable framework — not a collection of one-off campaigns. Every component was designed to be replicated across new markets without starting from scratch.
200+ email accounts across 10+ SDRs
Each SDR received dedicated domains and inboxes, all warming simultaneously. Deliverability monitoring enforced a 98%+ warmup threshold per inbox — any inbox that dipped was paused immediately.
125,000+ prospects across 25+ markets
Car dealers, fleet managers, and automotive businesses sourced through Apollo, enriched through Clay, and verified against Aviloo's Salesforce CRM to exclude existing customers.
8+ languages, native-quality copy
Every campaign was written in the target market's language with culturally relevant messaging. German campaigns referenced TÜV certification (high-trust signal). Italian campaigns timed to Autopromotec.
Salesforce + MasterInbox + AI routing
MasterInbox centralized replies across all SDR accounts into one dashboard. AI categorization flagged positive replies instantly. Qualified leads pushed to Salesforce for seamless handoff to Aviloo's sales team.

How the Results Compounded
The first campaigns launched in spring 2025 targeting core European markets. From there, the system expanded month by month — each new market building on the infrastructure and learnings from the last.
Core European markets live
Campaigns launched in Germany, UK, Ireland, and Netherlands. First positive replies from car dealers requesting demos and pricing.
Multi-language expansion
French, Italian, Spanish, and Portuguese campaigns go live. New SDRs onboarded with dedicated infrastructure. Event campaigns for NADA and Used Car Week drive booth traffic.
Full-scale operations
25+ markets active. 100 campaigns running across all SDRs. 16 positive replies in just 2 days — the system was compounding.
Record-breaking momentum
10 confirmed positive replies in a single day — a new record. Event campaigns for Autopromotec (Italy) and Fleet Europe drive targeted meeting bookings.
Advanced tooling deployed
AI reply handling agent, VIN-based targeting for hyper-specific outreach, and automated LinkedIn monitoring for fresh signals. Confirmed closed deals flowing from cold email.

Event-Driven Campaigns
One of the unique aspects of Aviloo's outbound system was event integration. The automotive industry revolves around major trade shows, and we built campaigns that turned these into outbound multipliers.
NADA Show
USPre-event outreach to attendees
Used Car Week
USTargeted dealer outreach
Digital Dealer
USConference-timed sequences
Autopromotec
ItalyItalian-language campaigns
Fleet Europe
EuropeFleet manager targeting
Each event campaign followed a specific playbook: scrape attendee and exhibitor lists, enrich contacts, send pre-event sequences that referenced the conference by name, and offer booth meetings or post-event follow-ups. These time-sensitive campaigns consistently outperformed always-on sequences.

The Copy That Worked
Across 100 campaigns and 8+ languages, certain patterns emerged. The most effective messaging combined Aviloo's unique credibility signals with market-specific pain points.
What Worked Across Markets
TÜV certification as trust signal — especially powerful in DACH markets where TÜV carries institutional weight.
The “garage story” angle — Aviloo was literally invented in a garage. Johannes, the founder, loved this storytelling approach: “The story telling angle (it was invented in a garage for a reason) is really good!”
Pain-led messaging — framing EV battery uncertainty as lost revenue for dealers, not a technical problem.
Event references — mentioning upcoming conferences created urgency and relevance that generic outreach couldn't match.
The key lesson: localization isn't just translation. German dealers respond to certification and engineering precision. Italian dealers respond to relationship-building and event connections. The copy engine adapted to each market's buying psychology.

The Orchestration Stack
Managing outbound across 25+ markets, 10+ SDRs, and 200+ email accounts requires serious orchestration. Here's the system we built and manage for Aviloo:
Sending & inbox rotation across 200+ accounts
Lead enrichment & multi-market data processing
Lead sourcing across global markets
MasterInbox
Centralized reply management across SDRs
CRM integration & pipeline tracking
LinkedIn engagement monitoring
Custom AI
Reply categorization & VIN-based targeting
Event Databases
Attendee scraping for conference campaigns
AI-powered lead qualification
This is system orchestration at its most ambitious: every tool purpose-built or configured for Aviloo's specific needs, all wired together into one cohesive operation that runs across time zones, languages, and markets.

Lessons Learned
Multi-market outbound requires parallel infrastructure, not sequential rollout. Each SDR needs dedicated domains and inboxes from day one.
Copy that works in German won’t work in French. Every market needs native-quality localization — not just translation.
Event-timed campaigns dramatically outperform always-on sequences when your buyers attend industry conferences.
Centralized reply management (MasterInbox) is essential when 10+ SDRs are sending from 200+ accounts. Without it, leads fall through the cracks.
The compound effect is real: 12 months of accumulated data, optimized copy, and refined targeting makes every new campaign better than the last.
This case study proves that cold email scales globally — when the system behind it is built for multi-market complexity from day one.
25+ countries. 8+ languages. 10+ SDRs. One system. 12 months and compounding.
