How to cancel Cannet by mail
Get your account details together
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to Cannet is only as good as the details it quotes.
Write the cancellation request
Postbye turns the request into a finished English letter headed “Subject: Cancellation Request – [your name]”: close the Cannet account, stop every charge and reply in writing.
Mail the letter with a receipt
Post it by certified mail to Cannet in Markham, Canada, using the exact address below, and note the tracking number.
Keep the delivery receipt
Keep the tracking record with your copy of the letter. If Cannet bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Cannet cancellation letter goes
Cannet can be reached by post at Warden Avenue 8601, Unit 3, L3R 0B0 Markham, Canada.
The envelope is going to Markham in Ontario, Canada, so the postcode L3R 0B0 must be on the front.
Your details go in a block headed by Account holder, Billing address on file and Email on file, and the opening line is “To Whom It May Concern,”.

Before you cancel Cannet, check these
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
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.
