Hint:
Plain text email has some advantages and limitations.
Format: The text part of the email cannot contain images or font formatting. You can use special characters to create line breaks and to add visual interest to the text part.
Links: In a plain text email, the entire URL of your links displays. If your links contain tracking parameters, the links can be long. To create shorter link URLs, use links without tracking parameters in the plain text version of your email.
Opens: Since plain text messages do not support tracking pixels, Engage cannot detect when a recipient opens the message. However, Engage can estimate the number of opens based on link tracking information for the message.
