How to cancel Mercer by mail
Get your account details together
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Mercer can only act on a request it can match to an account.
Write the cancellation request
The request is prepared in French (template fr), under the subject line “Objet : Demande d'annulation – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Send it by certified mail
Take the letter to the post office and ask for certified delivery to 28700 Béville-le-Comte. Keep the tracking number it gives you.
Save the tracking record
Once the letter is delivered, the date on the receipt is the date Mercer was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Mercer cancellation letter goes
For a letter to Mercer, use TSA 51801, 28700 Béville-le-Comte, France.
“TSA 51801” is a post-office box or mail-sorting line, so it takes post and not couriers: certified mail is the right way to reach it.
Inside, the salutation reads “À qui de droit,”, followed by your details under Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

Before you cancel Mercer, 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
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
