Hello, if your account is already functioning properly you can ignore this message.
Otherwise your account has been activated. We do recommend that you change your password and enable 2FA as a part of this process.
Please note that sometimes there is a subsequent login issue with GitHub. The usual solution for this issue is the following steps.
1. Login to Netlify using the email address and password only. If you do not have a password configured, you can add one by using the password reset form.
2. Once logged into Netlify with the email address and password, then change the GitHub account associated with this email address here: Netlify
3. Log out of Netlify.
Once this is done, you should be able to log into Netlify using GitHub or the email address. Both methods of login should work now. If they do not or if there are any other questions, please let us know.
