Your account can be linked to as many email addresses as you like. Having multiple email addresses helps users and organizations make connections and ensure you're receiving the most benefit from connections on the platform.
Adding email addresses
To add an email address, go to your Account Settings > Profile and enter the new email address. When you add it, a confirmation/validation email will be sent to that address. To validate you must click the link in that email. If you have trouble receiving your first validation request, you can resend a validation email from the Account Settings.
Can't add an email address
If you receive an error, it's possible an email is registered to an inactive account that requires merging with your current account. See the help document on merging accounts for more information or contact support for further help.
Your account has one primary email, which is the email address to which you will receive notifications and "from" which any client-facing emails will be sent. If you organization requires journaling of email messages you may be required to specify your managed email address as your primary email.
