Email Extractor Online is a powerful Chrome extension developed by X2Emails. It is a free tool that allows users to extract email addresses and phone numbers from online Facebook profiles.

With this extension, users can extract the details of group members and find their verified professional email addresses, designations, locations, company names, and domains. The tool claims to help users find up to 80% of the emails of group members. To maximize results, it is recommended to scrape multiple Facebook groups with more than 10,000 members in each group.

To scrape Facebook groups, users can simply use the Chrome extension to extract publicly available member information. The extracted data includes first names, last names, photo URLs, designations, company names, company domain names, profile URLs, profile IDs, email addresses (the number of emails found varies from group to group), and user locations (city, state, and country).

The extracted data can be used to build custom Facebook audiences for targeted advertisements or to reach out to group members via email or messages. Users also have the option to download the data in CSV format. To access the extension, users can sign up for a free account key on the X2Emails website.

Please note that the time taken to find email addresses increases with the number of profiles scraped, and there is no requirement to authenticate or share Facebook account details to use this extension.
