Go to your Settings page and open the Email Aliases section. Add the email address of the account you want to merge into your main account.
Important:
You must have access to the inbox of the email being merged.
You can only merge accounts you personally own.
A confirmation email will be sent — you must click the link to complete the merge.
Once merged, all promos, subscriptions, and invites will be consolidated into the main account.
This action is permanent and cannot be undone.
This is available for recipient promo accounts only.
