How to cancel Authentic by mail
Gather your account details
Authentic 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.
Put the request in writing
Your Postbye letter to Authentic asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Subscription termination – Authentic”. It comes from our English template.
Mail it with tracking
Take the letter to the post office and ask for certified delivery to 10018 New York. Keep the tracking number it gives you.
Save the tracking record
It shows the date Authentic received your letter. Check your next statement: no Authentic charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Authentic cancellation letter goes
Authentic takes its post at Broadway 1411, floor 21, New York 10018, which is where a cancellation letter belongs.
ZIP code 10018 places the address in New York, in the United States.

Before you cancel Authentic, check these
- 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.
- Use the same name and email as on the account. A mismatch can delay the request.
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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
