How to cancel Nebula by mail
Note your account details
You will need the email address on the account, the plan name and, if you can find it, the billing partner shown on your latest statement. Use exactly the details Nebula holds, so the request can be matched to your account.
Set out the request
Postbye turns the request into a finished English letter headed “Subject: Subscription termination – Nebula”: close the Nebula account, stop every charge and reply in writing.
Send it by certified mail
Take the letter to the post office and ask for certified delivery to 80217 Denver. Keep the tracking number it gives you.
File the delivery record
The receipt dates your request. Look at your next statement for any Nebula charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Nebula cancellation letter goes
Nebula can be reached by post at PO Box 5426, Denver, CO 80217.
“PO Box 5426” 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.
The database also lists 4201 Wilshire Boulevard Suite 615, Los Angeles 90010 for Nebula. Use the first address above unless your agreement names this one.
The letter is addressed “To Whom It May Concern,” and its details block uses the labels Name, Address and E-mail.

Before you cancel Nebula, check these
- Bundles and add-on channels can be billed separately from the base plan. Ask for every line to be cancelled.
- Check the billing date on your statement and send the request well before it, so the cancellation lands inside the current period.
- If an app store, phone carrier or TV provider bills you, the service itself cannot cancel it. Cancel with the billing partner as well.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a streaming or entertainment subscription
Streaming plans renew silently each month, and many are billed by a partner such as an app store or a TV provider rather than the service itself, so the request has to reach whoever actually bills you.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
