How to Extract Emails from Domains Listed in Google Sheets?

I have a Google Sheets document with a list of domains in one column. How can I utilize Google Sheets or any internet-based tool to automatically extract email addresses associated with these domains and populate them in a separate column? I need a solution that efficiently scans each website for contact information and retrieves the emails, streamlining the process without manual data entry. Any suggestions on online tools, add-ons, or scripts that can accomplish this task seamlessly?
