Verifying your email addresses
To help secure your Shopify admin, make sure that store owner and the staff have verified email addresses. Each store owner can verify only their own email address.
From your Shopify admin, click your username and account picture.
Click Your account or Your profile.
In the email verification banner, click Send verification email. If you don't see this banner, then your email is already verified.
From your email account, open the email and follow its instructions.
