How to cancel Udomi by mail
Gather your account details
Have the name and email on the account and, if you have one, an account or customer number to hand. The details in the letter need to match what Udomi has on file.
Prepare the letter
Postbye turns the request into a finished English letter headed “Subject: Subscription termination – Udomi”: close the Udomi account, stop every charge and reply in writing.
Send it by certified mail
Mail the letter by certified mail to the San Francisco address in the next section, and keep the tracking number.
Save the tracking record
File the receipt with the letter. A Udomi 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.

Before you cancel Udomi, 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
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.
