Email Scraper for Mail Merge is a free extension to Google's own email merge tool that makes it easy to collect names and emails from web pages for mass email marketing.

Once you start, you'll see a progress bar and a message in your toolbox that says, "Start Scraping." This means you can start scraping the web page and your spreadsheet will start to fill up with names and emails.

You'll see a message in your toolbox when you paste the URL that says, "URL Copied." You can try pasting it again. If you still see the same message, try using the paste button instead. This means you can start scraping the web page.
