How to cancel Idom by mail
Get your account details together
Idom will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Prepare the letter
Postbye writes the letter in French from our French template, because Idom's address is in Mayotte. It opens with the subject line “Objet : Demande d'annulation – [your name]” and asks Idom to end the subscription, stop all further charges and confirm in writing.
Post the letter
Mail the letter by certified mail to the Mamoudzou address in the next section, and keep the tracking number.
Keep the delivery receipt
Once the letter is delivered, the date on the receipt is the date Idom 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 Idom cancellation letter goes
Idom takes its post at 12 Centre Amatoula, 97600 Mamoudzou, Mayotte, which is where a cancellation letter belongs.
Mamoudzou is in Canton de Mamoudzou-3, Mayotte; the postal code to quote is 97600.
The letter greets the reader with “À qui de droit,”; your own details sit under the labels Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

Before you cancel Idom, check these
- 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.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
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 phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
