How to cancel Seazon by mail
Find your account details
You will need the name and email on the account and, if you have one, an account or customer number. Use exactly the details Seazon holds, so the request can be matched to your account.
Draft the request
Postbye writes the letter in French from our French template, because Seazon's address is in France. It opens with the subject line “Objet : Demande d'annulation – [your name]” and asks Seazon to end the subscription, stop all further charges and confirm in writing.
Mail the letter with a receipt
Mail the letter by certified mail to the Paris address in the next section, and keep the tracking number.
Keep proof the letter arrived
It shows the date Seazon received your letter. Check your next statement: no Seazon charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Seazon, 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.
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.
