I have tried that, created blank token prior to the for each row activity, used append and right after the for each i guess the token gets overwritten by the last or the first row of the query. I have not tried filling out pdf inside the for each row activity. In the Email you see I only see one row data in the token.

The 3 tokens you create need to be multi-value tokens. It looks like you didn't check that box when you created them. Then you want to set your action inside the For Each Row loop to append.

Done all that, here are the screenshots i appreciate what i might be missing here ? The email i receive after the loop has only one row of the value, although query returns 4 rows.
