How to cancel Smacl by mail
Gather your account details
Start with the policy number, the name on the policy and the date you want cover to end, so the request to Smacl names the right account the first time.
Write the cancellation request
Smacl is based in France, so the letter goes out in French, built from our French template. Subject line: “Objet : Demande d'annulation – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Post it with proof of delivery
Take the letter to the post office and ask for certified delivery to 44300 Nantes. Keep the tracking number it gives you.
File the delivery record
File the receipt with the letter. A Smacl charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Smacl cancellation letter goes
For a letter to Smacl, use Route de Gachet 31, 44300 Nantes, France.

Your details go in a block headed by Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré, and the opening line is “À qui de droit,”.

Cancelling a insurance or protection plan
Insurers cancel by policy and by effective date, so the request has to name the policy number and the date cover should stop, ideally after replacement cover is in place.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
