Thank you for reaching out to us. The main Constant Contact site is not meant to be accessed or used from mobile devices such as smartphones or tablets, so when working on the iPad, you'll definitely want to use the app. Currently, the mobile app does not support adding multiple email addresses or uploading files of contacts, so you will need to login to the site on your desktop or laptop computer to do this. Our apologies for any inconvenience this may cause. Please let us know if we can assist you further!
