I just used AI to help a client with a deceased spouse stop snail-mail solicitations. It was upsetting and disruptive. So I drafted a uniform letter with name and address merge codes, saying I am the attorney for the estate and they would get no more money. I drafted another master envelope with the same merge codes. I scanned all the return envelopes (asking for money) into a PDF, then asked my AI to create a *.csv file with all the names and addresses. I then ran a merge, printed the letters and envelopes, and sent those out. After that, I added more envelopes, asked AI to add the new names and addresses to the old *.csv, ignoring duplicates, and telling me which line items were new. Run the merge on those line items, print and mail. Ad infinitum until the deceased's name is longer on the mailing lists being sold.
