How to cancel Cube Smart 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 Cube Smart is only as good as the details it quotes.
Write your request
Ask Cube Smart 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 – Cube Smart”.
Post the letter
Use certified mail for the 19355 Malvern address in the next section, so the post office records the delivery. Write down the tracking number.
File the delivery record
File the receipt with the letter. A Cube Smart charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.

Every address we hold for Cube Smart, with the envelope wording
Before you cancel Cube Smart, 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
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 mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
