SimpliSafe Cancellation Letter

Skip the printer and the post office. We fill in this letter, you sign it on your phone, and we mail it USPS Certified for $29.

Use this SimpliSafe cancellation letter to give SimpliSafe written notice that you're cancelling. SimpliSafe accepts written notice by mail, and a signed letter sent certified gives you proof of the date.

What to put in your SimpliSafe cancellation letter

  • Your full name as it appears on the SimpliSafe account.
  • Your account or member number.
  • The mailing address on the account.
  • A plain statement that you are cancelling, and the date it takes effect.
  • A request to stop all billing after that date.
  • A request for written confirmation by email and mail.
  • Your signature and the date.

The sources we checked say SimpliSafe also asks for:

  • Request must come from the Account Owner
  • Account holder security questions or Safe Word verification (SimpliSafe may call to confirm a written request)
  • Requested future cancellation date, if not immediate (optional)

Where to mail your SimpliSafe cancellation letter

The mailing address in our sources is: SimpliSafe, Inc., 100 Summer Street, 3rd Floor, Boston, MA 02110.

Notice period: None. Notice is effective upon SimpliSafe's receipt and confirmation; cancelling before the billing date avoids the next month's charge..

Why send it USPS Certified Mail

USPS Certified Mail gives you a mailing receipt and a tracking number, and the Postal Service records when the letter is delivered. That record is what you point to if the company says it never got your notice.

Some contracts require certified mail. Others only ask for written notice, and certified mail is still the safest way to send it. Some contracts count notice from the day the letter arrives and others from the postmark date. The USPS record shows both.

Regular mail leaves you with nothing to show. A letter can sit in a mailroom, get misrouted or get thrown away, and you have no way to prove when, or whether, it arrived.

When we mail a letter for you, it goes USPS Certified within one business day of your order, and we email you the tracking number. You can follow it on the USPS site until it's delivered. The price is $29, paid when you order.
