Unfortunately, Avery cannot merge accounts or order history to another existing Avery account. If you would like to merge saved projects from one Avery account to another you will need to contact our Avery support team at 1-800-462-8379 or chat with us at avery.com/contact.
Please provide the two emails with the projects that you would like merged into the account of your choice.
Note: if you have 5 or less projects on the account, you will need to transfer them over yourself. Check out our article here on how to do that: Transfer Projects To a New or Existing Avery Account
