What Day to send Direct mail?? - Out of state owners...

Hello BP Fam,

I am getting ready to send out my out of state absentee list next week and was trying to decide what day is best to stick them in the mail. I know everything must be tracked and I will do so myself, but I am sure people will have tried out different days of the week  and tracked them for years...... @Michael Quarles   I am starting with hand written letters to try and get the phone ringing and will transition  into mailing services of letters and postcards as I get busy and put systems in place. Thoughts, advice, input....? Thanks all and have a GRATEFUL day!
