Email wording & the email log — See it before it sends
Beside the editor, the same email renders twice from the same real record in your workspace: Yours and RowFold's default. Flip between them and the only thing that changes is your wording. The preview says which record it drew from, so you can tell whether a merge field is actually resolving rather than guessing.
It renders the whole email, including the parts you can't edit — the table of answers on an acknowledgement, the approve and decline buttons on an approval. That's deliberate: your wording is the opening of the message, and the parts that let somebody act on it always survive.
