When creating a company profile, you will be prompted to list an “admin email”. If in doubt, the Clutch team will default to this email address for ongoing communications.
No. Only the Clutch team will have access to your email address, and it will not be posted on your company's public profile.
If you created a Clutch user account using your personal LinkedIn but did not provide an admin email address, Clutch will use the email address that is associated with your LinkedIn account.
