How to cancel AppContacter by mail
Collect the details you need
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 AppContacter is only as good as the details it quotes.
Prepare the letter
Ask AppContacter to cancel the account, stop all further charges and confirm in writing. Postbye prepares the letter from our English template, with the subject line “Subject: Subscription termination – AppContacter”.
Send it by certified mail
Mail the letter by certified mail to the Miami address in the next section, and keep the tracking number.
Keep the delivery receipt
Keep the tracking record with your copy of the letter. If AppContacter bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel AppContacter, check these
- 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.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.

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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
