How to cancel Cmaj by mail
Start with your account details
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Cmaj names the right account the first time.
Prepare the letter
Ask Cmaj to cancel the account, stop all further charges and confirm in writing. Postbye prepares the letter from our English template, with the subject line “Subject: Cancellation Request – [your name]”.
Send the letter by certified mail
Take the letter to the post office and ask for certified delivery to K1J 9B9 Ottawa. Keep the tracking number it gives you.
File the delivery record
The receipt dates your request. Look at your next statement for any Cmaj charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Cmaj cancellation letter goes
Written requests to Cmaj go to Blair Towers Place 1410, Suite 500, K1J 9B9 Ottawa, Canada.
The envelope is going to Ottawa in Ontario, Canada, so the postcode K1J 9B9 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 Cmaj, check these
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- 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.
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
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
