How to cancel Fizzer by mail
Collect the details you need
Have the name and email on the account and, if you have one, an account or customer number to hand. The details in the letter need to match what Fizzer has on file.
Write the cancellation request
Postbye drafts the request in French, the language of France, with “Objet : Demande d'annulation – [your name]” as the subject line. It asks Fizzer to close the subscription, stop billing and confirm in writing.
Send the letter by certified mail
Send it certified to Paris, France, copying the address from the next section letter for letter, and keep the receipt slip.
Hold on to the receipt
It shows the date Fizzer received your letter. Check your next statement: no Fizzer charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Fizzer, check these
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
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.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
