A plain text email is created automatically for all marketing emails. This version is only sent to a recipient if the rich text version isn't supported in their email client. You can customize the plain text version of your email in the Plain text tab in the content editor.
Please note: after the plain text email is customized, it won't update with any new content changes made to the rich text version.
To customize the plain text version of your email:
If you want the links in your plain text email to be tracked and formatted correctly, ensure that each link's text and URL conform to one of the following formats:
text^https://example.com
text(https://example.com)
text:https://example.com
text:https://example.com
text https://example.com
You must also turn click tracking on for plain text emails in your marketing email settings. Learn more about how to manage your email tracking settings.
