Return address

For Probate lettters…I hand wrote the to address on the envelope. Should I NOT put a return address on it? If so, should I hand write that to?

I just prepared 30 letters tonight and hand-wrote my return address on each of them. In the end, it is the content of my letters that get my phone ringing. I do agree, however, that you should hand address your envelopes so that it doesn’t look like junk mail.
