How to cancel Helium by mail
Get your account details together
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to Helium is only as good as the details it quotes.
Set out the request
Postbye drafts the request in French, the language of France, with “Objet : Demande d'annulation – [your name]” as the subject line. It asks Helium to close the subscription, stop billing and confirm in writing.
Send the letter by certified mail
Take the letter to the post office and ask for certified delivery to 51100 Reims. Keep the tracking number it gives you.
Keep proof the letter arrived
Delivery confirmation is your evidence that Helium was asked. Watch the next statement or two for any further Helium charge.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Helium cancellation letter goes
Helium can be reached by post at Rue Léon Patoux 4, 51100 Reims, France.
Copy the postal code 51100 exactly: it is what routes the letter to Grand Est, France.
The letter is addressed “À qui de droit,” and its details block uses the labels Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

Before you cancel Helium, check these
- Check your next statement: no charge should appear after the cancellation date.
- 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.
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 letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
