How to cancel Omna by mail
Start with your account details
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Omna is the easiest one to set aside.
Write your request
Ask Omna 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 – Omna”.
Send it by certified mail
Send the letter to the Wilmington mailing address shown below by certified mail. Keep the tracking number safe.
Hold on to the receipt
Delivery confirmation is your evidence that Omna was asked. Watch the next statement or two for any further Omna charge.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Omna cancellation letter goes
Omna takes its post at 3524 Silverside Road, Suite 35B, Wilmington, DE 19810-4929, which is where a cancellation letter belongs.
Wilmington is in Delaware (ZIP 19810-4929), a domestic address for certified mail within the United States.
Your details go in a block headed by Name, Address and E-mail, and the opening line is “To Whom It May Concern,”.

Before you cancel Omna, 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
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 phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
