The Text Only option allows you to access the WYSIWYG editor to create and format a simple email message. This email version does not contain or offer any branding graphics or images.
In Salesforce Marketing Cloud Content Builder, how do I create a text only email?
In Create Email, select Text Only from the drop-down menu.
Under Define Email Properties, give the email a descriptive Name.
Select a Location where you will save the email.
Enter the Subject of the email. The subject is required.
Note: After entering the Subject, click the Save button that appears when you click into the Subject field; otherwise, it will not save.
Enter the email text.
If your email or send classification do not include required Marketing Cloud anti-spam coding for the Phyiscal Mailing Address, Profile Center, and Track Opens, add them to the message.
