Before you can send any email campaigns with EXM, you must configure the default settings to create a manager root.
In the Default settings dialog box, specify the default settings according to the descriptions below. When you specify and save the settings, EXM creates the default manager root in the sitecore/content/Email folder.
You can edit the EXM default settings either in the EXM application or in the Content Editor.
The website address of the Content Delivery server.
This URL is used in all the links in the email message.
Preview base URL
In a scaled environment, internal links from test email messages point to the Base URL by default.
To point the links to a different server, specify its URL in this setting.
The email address that you want to appear in the From field of your email messages.
If you are using the Sitecore MTA as your provider, you must add the domain of the from email address to the list of domains, before you can save the changes.
The name that you want to appear as the From name on your email messages.
The email address that you want the replies from recipients sent to.
Global opt-out list
A static contact list that contains contacts who click the Unsubscribe from all link.
The contacts on this list will never receive another email message from EXM, even if the contact appears in a list that you have included in an email campaign.
To change this default list, click Browse to select a different list.
