How to cancel Lactu by mail
Collect the details you need
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Lactu can only act on a request it can match to an account.
Prepare the letter
Postbye writes the letter in French from our French template, because Lactu's address is in France. It opens with the subject line “Objet : Demande d'annulation – [your name]” and asks Lactu to end the subscription, stop all further charges and confirm in writing.
Send the letter by certified mail
Mail the letter by certified mail to the Lille address in the next section, and keep the tracking number.
Keep proof the letter arrived
It shows the date Lactu received your letter. Check your next statement: no Lactu charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Lactu cancellation letter goes
Lactu lists CS 90006, 59718 Lille, France as its mailing address.
Copy the postal code 59718 exactly: it is what routes the letter to Hauts-de-France, 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 Lactu, check these
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
- Check your next statement: no charge should appear after the cancellation date.
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
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
