I've read the other post, but I'm still really confused how to do this.

I have a data source that is sorted by my key, I have my normal base
document, but I don't know how to tell my document this is my key or how to
tell it that if this key is not the same as my current record then make a new
email.

Please help and be more basic in the insturctions. I don't know anything
about togle codes etc. But I'm in serious need to send an email up to clean
up data without spending days doing individual emails.

Please help.
