要約

When sending an email using the Send Email component in an Automation rule, you may notice that text formatting and styling are not retained in the actual email if you use smart values to insert issue content in the body of the email. You will also see the Jira wiki markups as they are in the email received making the email difficult to read.

環境

Jira Cloud

原因

This is because using smart values in the body of the email inserts the data in Jira wiki format, and when this is sent to an email inbox, the format is not recognized. 

ソリューション

You would need to convert the Jira format to HTML format for the context to be formatted correctly in the email as well. This can be achieved by appending the smart value with .html. Using this converts the Jira formatted text to HTML, and content is rendered with proper formatting and styling in the email.
Example: 

{{issue.description.html}}
