How to cancel Adblock by mail
Collect the details you need
Adblock will look your account up from what the letter says, so check the email address you signed up with, the plan name and the date of your last payment first.
Prepare the letter
Your Postbye letter to Adblock asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Subscription termination – Adblock”. It comes from our English template.
Send the letter by certified mail
Send the letter to the Houston mailing address shown below by certified mail. Keep the tracking number safe.
Keep the proof of delivery
It shows the date Adblock received your letter. Check your next statement: no Adblock charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Adblock, check these
- Most plans renew yearly. Find the renewal date on your last receipt and write before it.
- Refund windows run from the purchase date, not the date you stop using the app. Check yours.
- Accounts bought through an app store or a reseller are cancelled there, not with the provider.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a VPN or privacy subscription
VPN and privacy tools tend to renew yearly and the renewal date is easy to forget, so the request should reach the provider before the next renewal and ask for written confirmation.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
