For your convenience, you can configure settings for a particular kind of email (e.g., marketing, transactional, etc.) and save it as an Email Type. Then when you choose that Email Type for a campaign, the settings you configured will be automatically applied. See below to learn how to create a custom Email Type if the preloaded Email Types don't suit your needs.
Access the Email Type Tab
Select the circle icon containing the first initial of your name in the upper right corner to view a drop-down list.
Select Admin from the drop-down list.
Select the Email Type tab or scroll through the tabs using the arrow on the right side of your screen to select the Email Type tab.
Add a New Email Type
Select Add New Email Type.
In the Email Type Settings box, choose an email type, enter a name for the new email type and a brief description. Select Add Email Type.
Update Settings Specific to the New Email Type
Select Edit for the setting you want to change.
Change the parameters for the setting, then select Update.
From the Template tab in Campaigns > Create or Campaigns > Manage, select the Email Type Manage link to jump directly to the settings associated with the email type selected for that campaign.
