I'll explain a little because I don't know if you finish understanding.
To go by steps, if I automate button for the following table, there is no problem:

The issue is that this table is all summarized, that is, the CEF group groups several lines where the clients that belong to it come out. The following table is the one I want.

The thing is that, if I make the button with the first table, including the fields exactly the same both in the table and in the button, the mail sends it correctly to an address, the one that appears. The problem is good with the second table, because the mail sends it repeatedly in a loop, and what I would like is to send only one mail with that table.
