How to cancel Spylix by mail
Note your account details
Spylix will look your account up from what the letter says, so check the account or subscription number, the email the plan was bought with and the address or devices it covers first.
Draft the request
State plainly that you want the Spylix account cancelled, further charges stopped and a written confirmation sent to you. Postbye sets this out in a ready English template (“Subject: Cancellation Request – [your name]”).
Post the letter
Address the envelope to Spylix, London, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Hold on to the receipt
Once the letter is delivered, the date on the receipt is the date Spylix was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.

- Keep copies of anything you return, such as a control panel or camera, and send it with tracking.
- Monitored plans can run on a fixed term. Check your agreement for the end date and any early-termination fee.

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.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
