Since spam filters watch for both HTML and plain text versions of a message, utilizing plain text alternatives is a great way to lower spam score. Blueshift has always automatically generated a plain-text version for every email template created on the Blueshift platform. Going forward, the Blueshift platform will also allow you to customize the system generated plain text content.
This feature is currently available in the HTML email editor. When you navigate to the ‘Content’ tab, you will see an additional set of tabs that allow you to specify the HTML, AMP and Plain Text content. When you navigate to the ‘Plain Text’ tab, you will be able to check the box which enables the editor below and allows you to override the system generated content with your own custom content. You will also be able to preview the plain text content on the left panel of this tab. To learn more about this feature, you can refer to this document.
