If I used inmateaid website to send a letter and picture last Friday night how long will it take for the inmate to receive it?

Usually 2-3 business days does the trick, but there are sometimes delays inside the facility mail room that are outside of anyone's control. Our letters have the InmateAid logo on the envelope and the mail staff knows that we only send letters and photos, there are no marketing pieces or anything that might delay delivery to the inmates.
