Email or send mail to an adult in jail

To keep people in custody safe and secure, we limit the kinds of mail allowed at our facilities. The fastest way to contact an adult in jail is by email. You can mail a letter, but there are strict rules.


King County uses Access Corrections to manage email. You need to set up a prepaid account at to send emails to adults at the Seattle and Kent facilities. Jail staff will screen your email, and if approved they will forward it to the person. You may also send photos via email. 

The cost of sending an email is set by Access Corrections. 

Adults in jail will not be able to reply by email or forward your email to anyone else. They will only be able to write letters, which are sent through the mail (U.S. Postal Service).

Postal mail

All mail must meet facility rules. To keep people in jail safe, we limit the kinds of mail we accept at our detention facilities. This also helps ensure fair treatment to everyone in our custody. Jail staff open and search all non-legal mail for prohibited items and content. We do so to stop criminal activity and to keep our facilities secure. 

Anybody in jail found in possession of prohibited items will have the item taken away. They may also face penalties for having received prohibited items from you. 

  • All mail must be delivered through the U.S. Postal Service. Items delivered from any other service, including UPS, FedEx, or Amazon delivery, will be denied and returned to sender. 
  • Correspondence between people in custody is prohibited and may cause the loss of mail privileges. This includes using a third-party, like a family member or friend, to try to deliver a letter to another person in jail (including at other secure detention facilities).
