How to cancel Mosso by mail
Gather your account details
Before writing, collect the account email, the domain or server name and the invoice number of the plan being cancelled. Mosso can only act on a request it can match to an account.
Put the request in writing
Postbye turns the request into a finished English letter headed “Subject: Subscription termination – Mosso”: close the Mosso account, stop every charge and reply in writing.
Post it with proof of delivery
Post it by certified mail to Mosso in Irving, United States, using the exact address below, and note the tracking number.
Keep proof the letter arrived
File the receipt with the letter. A Mosso 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 Mosso cancellation letter goes
Mosso can be reached by post at 3220 Executive Ridge Drive, Suite 101, Irving, TX 75038.
With ZIP 75038, the address sits in Texas and the letter never leaves the United States postal system.
Your name, address and email appear in a short block labelled Name, Address and E-mail, under the greeting “To Whom It May Concern,”.

Before you cancel Mosso, check these
- Download your data before the cancellation date. Servers are usually wiped soon after.
- If the domain moves to another host, transfer it first, then cancel the hosting.
- Domains, SSL certificates and backups can renew separately. List each service you want to stop.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a hosting or cloud-storage plan
Hosting and cloud plans are often prepaid for a term and renew with domains and add-ons on separate dates, so the request should list each service that should stop renewing.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
