How to cancel Siege by mail
Get your account details together
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Siege can only act on a request it can match to an account.
Draft the request
Ask Siege 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: Subscription termination – Siege”.
Mail the letter with a receipt
Address the envelope to Siege, Austin, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Save the tracking record
Keep the tracking record with your copy of the letter. If Siege 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.

Before you cancel Siege, 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
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
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.
