Verify a debt letter before calling it junk mail

Do not treat a letter about money owed as junk mail until you have checked it. According to the CFPB, a legitimate collector can identify its company and give information about the claimed debt, so ask for both before you share any personal financial details. A marketing removal request is the wrong tool for this letter and will not answer the question it raises.

Check the claim before you act on it

Keep the letter and its envelope. Note who says it is collecting, who it says is owed, the amount and any response date.
Do not call a number or open a link printed on the letter yet. Find the company's contact details on your own, then ask it to identify itself and give information about the claimed debt.
Hold back account numbers, your Social Security number and bank details until the company has identified itself and the debt information matches something you can check.
Compare what they tell you with your own records. Write down who you spoke to and what they said they would send.
If the letter looks like a scam or mail fraud, you can report it to the Postal Inspection Service. Keep the letter and envelope either way.

Why an opt-out request does not belong here

A collection letter concerns a claimed obligation. It is not an advertisement. A request to stop marketing mail is a different request and does not pause any date the letter gives. Treat that date as real until you have confirmed otherwise.

A letter can look like an ad and still be a real collection notice. Another can look official and turn out to be a scam. A name, a logo or an urgent tone will not tell you which.
