What You Can (and Can’t) Send to an Inmate at Cass County Jail — Mail Rules & What Happens After You Mail It
Sending mail to someone at Cass County Jail? Keep it simple. The jail accepts letters and photos through the U.S. Postal Service, but everything needs a complete return address—otherwise it can't be processed or returned if there's a problem.
Inmates at Cass County Jail can receive letters through the U.S. Postal Service. Writing for the first time? Keep it straightforward - a plain letter that follows postal rules and won't raise security concerns.
Photos are allowed too, as long as they come through U.S. Mail. Not sure if something counts as "mail" or an "item"? Play it safe and stick to standard printed photos tucked inside a letter.
- ✓ First and last name (return address)
- ✓ Full street address
- ✓ City
- ✓ State
- ✓ ZIP Code
Prohibited: Mail containing pornographic material, or anything that could create sexual-harassment concerns, is not allowed and will be destroyed.
Skip the perfume: Mail with bio-hazard indicators - including perfume odors or lipstick marks - won't be accepted.
The mailroom here is strict: inmates can only receive letters and photos. Send anything else, and it'll be rejected - not delivered.
When your envelope arrives, staff will open and inspect it for contraband. This screening is how the jail keeps prohibited items from getting inside.
After inspection, incoming mail gets scanned and delivered electronically. So even though you send a physical letter, your loved one may receive a digital copy rather than the original paper.
If the person you're writing has been transferred to a state institution, mail addressed to them at Cass County Jail will be returned to you. This is why the return address matters - without it, there's no way to get the letter back to you.
If the inmate is still in Cass County Sheriff's Office custody but housed at a different facility, Cass County will forward or hand-deliver the mail within 48 hours. This helps keep letters from getting stuck during temporary housing moves.
Outgoing mail from your loved one gets picked up by the U.S. Postal Service - except on holidays and weekends. Waiting on a response? Those gaps can add a couple of extra days even when everything's moving normally.
The jail shouldn't hold outgoing mail longer than 24 hours, with a few exceptions: weekends, holidays, or times when staff can't process it. If a letter feels late, those processing windows are usually the reason.
Don't try to pass messages between incarcerated people through the mail. Correspondence with inmates at other institutions - or even with other inmates at Cass County Jail - is prohibited. Any inmate-to-inmate mail will be returned.
- ✓ Write a complete return address every time (first/last name, street address, city, state, ZIP)
- ✓ Keep envelopes and paper free of perfume, lipstick, or anything that could be treated as a bio-hazard indicator
- ✓ Keep a copy of important letters or photos for your records in case the mail is returned
