How do I know when inmates I send letters to have received them

We estimate that it takes 2-3 business days to make it to the jail. Once there, the staff opens and reads each piece of mail and inspects it for contraband. Any delay that occurs at the facility is out of our control. We make no guarantees as to how long it will take as there are thousands of facilities and none of them do things the same way.Please be patient, if the ID number and facility are correct we are 100% reliable.Mail call is Monday - Friday in most places.The only way you will know if when he responds, unless the letter is returned to us - in that event we will investigate the reason and notify you of your options.
