If you want to bring any changes to your contact list, such as its name and sender email address, you may do so.
Change the name and sender email of my contact list
Click on the “Contact Lists” tab and locate the list you would like to edit. In the left menu, click on the “Manage emails” option and then on “Set sender name & email address.” Keep in mind that the sender’s email address will appear in the top of your campaign when it’s received by your subscribers.
Change the name of my contact list
Click on the “Contact Lists” tab and locate the list to be modified. Click on the “Rename” option which is directly below the list’s name (first link on the left).
Note that you may also change the name of a list when you are in the list itself, and this, by clicking on the “Rename” option found just below the list’s name.
