Where to send your Adblock cancellation letter

Read the addresses on this page next to the full guide to cancelling Adblock.

The addresses we hold

Everything we hold on where Adblock takes its post: the 77080 Houston delivery point for a cancellation letter, any second address, and how to send it so the delivery is on record.

Where the letter goesMailing address

Adblock12333 Sowden RoadSuite BHouston 77080

Adblock takes its post at this Houston address (ZIP 77080).

How to address the envelope

  1. Write the address as printed

    Copy 12333 Sowden Road, Suite B, Houston 77080 letter for letter. A wrong digit in 77080 is enough to send the letter on a detour.

  2. Add the return address

    Your name and postal address go top-left on the front (or the back flap). If the letter cannot be delivered it comes back to you, which is itself evidence of the attempt.

  3. Send it certified

    At the counter, certified mail costs a fee on top of the postage and comes with a mailing receipt and a delivery record. The tracking number on the green label is what you follow.

  4. File the receipt with your copy

    The postmarked receipt, the tracking record and your signed copy of the letter are the set that proves the request.

The letter to send

Copy the letter below onto one page, fill in the email address you signed up with, the plan name and the date of your last payment, and it is ready for the envelope. Our template builds the same letter on screen.
