Key Data Points Included

• Phone Number (optional)

How to Find Emails Yourself

While providers save time, some teams prefer DIY methods:

• LinkedIn Research: Search titles like CEO, Founder, or Marketing Manager in Poland and enrich profiles with email verification tools.

• Email Guessing: Use common formats (e.g., firstname.lastname@company.pl) with advanced search operators.

• Public Records & Business Directories: Some Polish business directories provide emails, but accuracy varies.

DIY methods are time-consuming and often yield incomplete or unverified emails, so they work best for small, highly targeted campaigns.

Tips for Usage of Polish Email Addresses?

• Segment your audience by industry, company size, or role for targeted campaigns.

• Personalize messages with the contact’s name and company details.

• Avoid spam triggers like long attachments or generic subject lines.

• Compliance: Ensure your campaigns comply with data regulations (like GDPR if applicable) and best practices for deliverability.

Important Considerations for 2026

• Targeting: Segment lists carefully to improve response rates. Generic campaigns are less effective.
