Cease and desist letter

A written, dated instruction to stop contacting you — across every channel, including the affiliates and the "different" company that calls next week.

By MCAFax · Last updated July 29, 2026 · How we source this

The point of this letter is not that it is scary. It is that it is dated. Before it, a broker calling you is a nuisance. After it, every contact happened after a written instruction to stop, from a party who kept a copy and knows when it was delivered. That is the line that changes the conversation with a regulator, and it is the line that makes most rooms move you to the do-not-call list, because you have become more expensive than you are worth.

Send it from an address you control, keep the sent copy, and if you can, send it in a way that produces a delivery record.

Read this first. MCAFax is not a law firm and this is not legal advice. These are starting points written in plain language — facts, dates and dollar figures are yours to fill in, and every claim you make in a letter should be one you can prove. If real money is on the line, or if anyone has threatened suit, have a lawyer in your state read it before you send it.

The letter

[DATE] [YOUR NAME] [YOUR BUSINESS NAME, IF ANY] [YOUR MAILING ADDRESS] [COMPANY NAME] [COMPANY ADDRESS, IF KNOWN] Re: Cease and desist — all contact To whom it may concern, This letter is a formal notice to cease and desist all contact with me and with [YOUR BUSINESS NAME], through every channel — telephone calls, text messages, voicemail including ringless voicemail, email, and physical mail. Place my telephone number(s) and email address(es) on your internal do-not-call list. This instruction extends to your affiliates, agents, lead vendors, and anyone contacting me on your behalf or on behalf of any funder you submit files to; please forward this notice to them. To the extent you claim any consent to contact me ever existed, by any means and through any channel, that consent is revoked as of the date of this letter. I am also requesting, in writing: 1. A copy of your written do-not-call policy. Callers making telephone solicitations are required to maintain one and to make it available on demand under 47 C.F.R. § 64.1200(d). 2. The full legal name and address of the entity that placed or directed the contacts, and of any funder or principal on whose behalf they were made. 3. The source of my contact information, and a copy of any record of consent you are relying on. For the record, contacts to date include: [DATE, TIME, NUMBER, WHAT WAS SAID] [DATE, TIME, NUMBER, WHAT WAS SAID] [DATE, TIME, NUMBER, WHAT WAS SAID] Further unsolicited contact after the date of this letter may violate applicable state or federal law, including — where it applies — the Telephone Consumer Protection Act, which provides for statutory damages of $500 to $1,500 per violation. I am keeping a dated record of all contact. Do not contact me again. [YOUR NAME] [YOUR BUSINESS NAME, IF ANY] [YOUR MAILING ADDRESS]

The parts that are doing the work

  • Every channel, named. "Stop calling" invites a text. The list closes that door, and it closes the ringless-voicemail door specifically, because that is the one people forget.
  • Affiliates and lead vendors. Your number was almost certainly bought from a list. Naming the chain is how the instruction follows the data instead of stopping at one room. Why they have your number at all explains where the list comes from.
  • Revocation of any claimed consent. Somewhere in a file there may be a checkbox you do not remember. This says: whatever it was, it is over as of today.
  • The do-not-call policy demand. A telephone solicitor is required to keep a written policy and produce it on request. Whether they do — and how fast — tells you a great deal about the shop, and an ignored demand is itself part of the record.
  • The dated contact list. Three lines from your log. It converts the letter from a form into a specific, evidenced complaint.

Note the two things this letter deliberately does not say: it does not claim your number is on the National Do Not Call Registry, and it does not claim it is a residential line. Business lines get less protection than home lines, and a letter should never assert a fact you cannot back. Say only what is true, and say it with dates.

The reporting is open. The network isn't — yet.

MCAFax is being built to do the thing you can't do from inside the room: make the phone stop. Members will check any broker against a shared, member-built database and send cease & desist letters from their own Gmail, with delivery proof on every one. Some laws, like the TCPA, put statutory damages on illegal calls — whether they apply to yours depends on your situation, and business lines get less protection than home ones. We're not a law firm. Sign-ups aren't open yet; the newsroom is, and it's free to read.
