Frequently Asked Questions

How many emails and profiles can I extract daily?

With COSLR’s Unlimited plan, you can extract as many profiles, emails, and other data as you like. There are no caps or additional charges. 

Won’t Linkedin limit me? Is it Safe?

COSLR mimics human behavior while collecting emails or profile data. We only use your profile when visiting different pages of search results with randomized pauses and behavior. This gives give the impression that you are actually manually visiting a user’s profile.

All downloads and extractions for your prospects happen on another server (not in your browser). This makes COSLR safe, even when using your personal LinkedIn account to extract hundreds or thousands of leads.
