How to find B2B clients in the Baltics

The Baltic markets are small enough that a focused B2B company can reach a large share of its potential clients directly, and open enough that the data to do it is public. What separates campaigns that bring deals from campaigns that burn a domain is preparation: a clear target, a clean list, a legal approach and honest measurement.

Start with the ideal client

Before collecting any data, describe who buys from you. Industry, company size, location, whether they have a website, and the problem you solve for them. Look at your best existing clients: what do they have in common? A short description such as "construction companies in Tallinn and Tartu with 10-50 employees" is far more useful than "SMEs in Estonia".

Where company data comes from

All three Baltic countries and Finland keep official business registers with company names, registration codes, addresses, legal forms and activity codes. Estonia's e-Business Register is a well-known example, and Latvia and Lithuania publish company data as open data. Activity codes (NACE, called EMTAK in Estonia) let you filter by industry, and register data can be combined with company websites to find general contact addresses.

Collecting and cleaning this data yourself takes time: different formats per country, duplicate records, inactive companies and missing emails. That is the work BalticLeads does. It holds 1.4 million companies from the business registers of Estonia, Latvia, Lithuania and Finland, about 744,000 of them with an email address.

Building the list

• Filter narrowly. Country, industry, city and size. A list of 500 relevant companies beats 20,000 random ones.
• Use company addresses. Prefer generic role addresses like info@ or sales@. Free and personal webmail addresses add legal risk and hurt deliverability.
• Split into segments. Each segment gets its own message. A dental clinic and a logistics company need different arguments.
• Remove existing clients and past opt-outs before every send.

The rules for cold outreach

Cold B2B email to companies is allowed on an opt-out basis in Estonia, Latvia and Lithuania; in Lithuania this has applied since 22 April 2026. In practice that means:

• Role addresses are company contact data. Addresses like info@ or sales@ belong to the company, not to a person.
• Named people are personal data. An address like jaan.tamm@company.ee is personal data under GDPR. If you contact named people, you need to inform them where you got their data and why, as required by Article 14 of GDPR.
• Every email needs an unsubscribe link. Make it one click, and make it work.
• Objections are honoured immediately. When a company asks to stop, it goes on a suppression list for all future campaigns.
• Identify yourself. A real sender name, company name and contact details in every message.

This is a summary for orientation, not legal advice. For your specific case, check with a lawyer.

Protecting deliverability

Legal is one side; inbox placement is the other. Send from a properly configured domain with SPF and DKIM, warm up new mailboxes, keep daily volumes per mailbox low and stop sending to addresses that bounce. Many teams use a separate domain for outreach so that their main domain's reputation is never at risk.

The BalticLeads workflow

1. Describe your ideal client. In AI search you write in plain words who you are looking for, and the platform turns it into filters.
2. Refine and check the count. Adjust industry, city and size until the list is focused.
3. Buy the database. You pay for the contacts you actually need, and the list is saved to your account.
4. Launch an email campaign. Each campaign is moderated before sending. Global opt-out and automatic unsubscribe handling are built in, and free or personal webmail addresses are hidden.
5. Handle replies. Move interested companies into your CRM and follow up quickly.

BalticLeads is built and run by our team, which is why we use it directly in client projects. If you prefer, we take on the whole process: targeting, copy, a landing page, outreach and Google and Meta ads. See B2B lead generation.

Writing the email

• Short: five to eight sentences.
• About their problem, not your company history.
• One clear next step: a reply, a short call or a link to a focused landing page.
• One or two polite follow-ups that add something new, then stop.
• In the language of the recipient: Estonian, Latvian, Lithuanian, Russian or English.

Measuring what works

Do not judge a campaign by open rates; they are unreliable because of privacy features in email clients. Track instead:

• Bounce rate, to keep the list and the domain healthy.
• Reply rate and positive replies per segment and per message.
• Meetings booked and deals closed, tracked in a CRM.
• Unsubscribes, as a signal that the targeting or the message is off.

Test one change at a time: a new segment or a new message, not both. After a few waves you will know which industries and arguments bring revenue, and you can add ads aimed at the same companies to reinforce the emails.
