How to cancel Smtpc by mail
Find your account details
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 Smtpc is only as good as the details it quotes.
Write your 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.
Post it with proof of delivery
Use certified mail for the 13010 Marseille address in the next section, so the post office records the delivery. Write down the tracking number.
Save the tracking record
Once the letter is delivered, the date on the receipt is the date Smtpc 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 Smtpc cancellation letter goes
For a letter to Smtpc, use Rue Arthur Scott 3, 13010 Marseille, France.
The postcode 13010 belongs to Provence-Alpes-Côte d'Azur, France, so this is where the envelope is delivered.
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,”.

Before you cancel Smtpc, 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
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.
