I want to use a single email to either send a new or updated item email. If I create a column containing a choice of two sentences (one indicates the email contains a new item and the other an update), is there a way to insert one of them in the body of an email when a condition is met? Or, is there a better way?
In your workflow, you would us an if/else branch to build a dynamic string (using the set workflow variable action) based on some condition. The key is to output the strings to the same variable. Then in your email body, you insert this variable into the body. Then when an item is submitted, based on the list metadata, it selects the appropriate string and inserts it into the email body.
