Thank you for reaching out to the Community. That is a great question! We do have a couple different options for account access in your account that include a Campaign Creator or an Account Manager. To view the different roles, you can click here for more information. If you are looking to give someone access to your account for editing emails, but not viewing your contacts, I would suggest the role of the Campaign Creator. The number of additional users you can add does depend on your pricing package. Please email us at social_support(at)constantcontact(dot)com with your username, a reference to this post and I would be happy to take a look and see what is available for you!
