How to cancel Fishbrain by mail

  1. Note 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 Fishbrain is the easiest one to set aside.

  2. Write the cancellation request

    Your Postbye letter to Fishbrain asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Subscription termination – Fishbrain”. It comes from our English template.

  3. Post it with proof of delivery

    Send it certified to Camden, United States, copying the address from the next section letter for letter, and keep the receipt slip.

  4. Hold on to the receipt

    Keep the tracking record with your copy of the letter. If Fishbrain 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.

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.

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.
