How to cancel Go3 by mail
Gather your account details
Go3 will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Put the request in writing
Your Postbye letter to Go3 asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Cancellation Request – [your name]”. It comes from our English template.
Send the letter by certified mail
Take the letter to the post office and ask for certified delivery to 11415 Tallinn. Keep the tracking number it gives you.
Hold on to the receipt
Keep the tracking record with your copy of the letter. If Go3 bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Go3 cancellation letter goes
Go3 can be reached by post at Peterburi tee 81, 11415 Tallinn, Estonia.
Tallinn is in Harju maakond, Estonia; the postal code to quote is 11415.
Inside, the salutation reads “To Whom It May Concern,”, followed by your details under Account holder, Billing address on file and Email on file.

Before you cancel Go3, 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
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
