Market overview
With 25,000 verified contacts, the Serbia Business Email Database is one of LeadsBlue's business email list datasets for Serbia. Serbia is the largest economy in the Western Balkans and a rapidly growing IT services hub. Belgrade is both the capital and commercial centre. Serbia has attracted major foreign investment in manufacturing (Stellantis/Fiat, Bosch, Continental) and IT services. The country has a significant tech talent base and growing startup ecosystem.
Key business hubs: Belgrade, Novi Sad (IT hub), Niš, Kragujevac (automotive).
Outreach strategy
Serbian B2B cold email in English works well for the IT sector. Serbian-language outreach is preferred for domestic companies. Belgrade's tech community is internationally oriented and growth-focused.
Compliance
Serbia has its own data protection law (Law on Personal Data Protection 2018) modelled on GDPR, enforced by the Commissioner for Information of Public Importance and Personal Data Protection. Legitimate interest applies for B2B cold email.
Cold email benchmarks by industry
Engagement varies by the recipient's industry. Benchmark open and reply rate ranges from the LeadsBlue study:
| Industry | Open rate | Reply rate |

| Technology & Software | 22-31% | 3.5-6.5% |
| Healthcare & Medical | 18-26% | 2.0-4.5% |
| Manufacturing & Engineering | 16-23% | 1.8-3.5% |

How to use this list effectively
- Verify before sending. B2B contact data decays roughly 2–3% per month as people change roles. Run the list through a verification pass to remove stale or invalid addresses before your first send.
- Segment by industry and role. Response rates improve sharply when the message matches the recipient's vertical and seniority — use the segment fields to tailor your copy rather than sending one generic message.
- Warm up the sending domain. Start with low daily volume from a dedicated sending domain and ramp gradually to protect deliverability.
- Follow a multi-touch cadence. Most replies come from the 2nd–4th touch; a short sequence over 2–3 weeks outperforms a single send.
- Respect compliance. Include a valid postal address and a working opt-out, and honour unsubscribe requests promptly (see compliance notes above).
