How to cancel Hsu by mail
Gather your account details
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Hsu is the easiest one to set aside.
Write the cancellation request
Ask Hsu 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]”.
Post the letter
Use certified mail for the 2000 Sydney address in the next section, so the post office records the delivery. Write down the tracking number.
Keep the delivery receipt
Delivery confirmation is your evidence that Hsu was asked. Watch the next statement or two for any further Hsu charge.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Hsu cancellation letter goes
Hsu can be reached by post at Locked Bag 3, 2000 Sydney, Australia.
“Locked Bag 3” is a post-office box or mail-sorting line, so it takes post and not couriers: certified mail is the right way to reach it.
Inside, the salutation reads “To Whom It May Concern,”, followed by your details under Account holder, Billing address on file and Email on file.

Before you cancel Hsu, 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
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
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.
