How to cancel 10x by mail
Get your account details together
Start with the name and email on the account and, if you have one, an account or customer number, so the request to 10x names the right account the first time.
Set out the request
State plainly that you want the 10x account cancelled, further charges stopped and a written confirmation sent to you. Postbye sets this out in a ready English template (“Subject: Subscription termination – 10x”).
Post it with proof of delivery
Post it by certified mail to 10x in Miami, United States, using the exact address below, and note the tracking number.
Keep proof the letter arrived
File the receipt with the letter. A 10x 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.
Where your 10x cancellation letter goes
For a letter to 10x, use Northeast 29th Avenue 18851, # 902, Miami 33180.
ZIP code 33180 places the address in Florida, in the United States.
Inside, the salutation reads “To Whom It May Concern,”, followed by your details under Name, Address and E-mail.

Before you cancel 10x, check these
- Use the same name and email as on the account. A mismatch can delay the request.
- Check your next statement: no charge should appear after the cancellation date.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
