How to cancel SimpliSafe by mail
Collect the details you need
You will need the account or subscription number, the email the plan was bought with and the address or devices it covers. Use exactly the details SimpliSafe holds, so the request can be matched to your account.
Put the request in writing
State plainly that you want the SimpliSafe account cancelled, further charges stopped and a written confirmation sent to you. Postbye sets this out in a ready English template (“Subject: Subscription termination – SimpliSafe”).
Send the letter by certified mail
Take the letter to the post office and ask for certified delivery to 02110 Boston. Keep the tracking number it gives you.
Keep the proof of delivery
File the receipt with the letter. A SimpliSafe charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your SimpliSafe cancellation letter goes
For a letter to SimpliSafe, use Summer Street 100, Boston 02110.
ZIP code 02110 places the address in Massachusetts, in the United States.
Your details go in a block headed by Name, Address and E-mail, and the opening line is “To Whom It May Concern,”.

Cancelling a security or identity-protection subscription
Security subscriptions often auto-renew and monitored plans can sit on a fixed contract term, so it matters when the request reaches the provider and whether it covers every device or location.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
SimpliSafe lets you cancel directly (phone or chat). A letter is the fallback that leaves a dated record when the direct route fails.
