You will be asked to log into your account to confirm this email address. Be sure to log in with your current primary email address.
We ask you to confirm your email address before sending invitations or requesting contacts at LinkedIn. You can have several email addresses, but one will need to be confirmed at all times to use the system.
If you have more than one email address, you can choose one to be your primary email address. This is the address you will log in with, and the address to which we will deliver all email messages regarding invitations and requests, and other system mail.
Thank you for using LinkedIn!

Personally, I hate LinkedIn emails. Blocking everything that appears to be from linkedin.com will not have any adverse impact on your life.
