How to cancel Checkdomain by mail

  1. Gather your account details

    Start with the name and email on the account and, if you have one, an account or customer number, so the request to Checkdomain names the right account the first time.

  2. Draft the request

    Because Checkdomain is dealt with in German, the letter is written in German (template de). Subject: “Betreff: Kündigungsanfrage – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.

  3. Send it by certified mail

    Use certified mail for the 23552 Lübeck address in the next section, so the post office records the delivery. Write down the tracking number.

  4. Hold on to the receipt

    Keep the tracking record with your copy of the letter. If Checkdomain 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 Checkdomain, 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

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.

Checkdomain cancellation questions

Where do I send my Checkdomain cancellation letter?

Address the letter to Checkdomain, Große Burgstraße 27/29, 23552 Lübeck, Germany.

Which language is my Checkdomain letter written in?

German. Checkdomain's address is in Germany, so the letter is prepared from the German template under the subject line “Betreff: Kündigungsanfrage – [your name]”.

What do I need to cancel Checkdomain?

Have the name and email on the account and, if you have one, an account or customer number to hand. The details in the letter need to match what Checkdomain has on file.

Will Checkdomain confirm my cancellation?

The letter asks Checkdomain to end the account, stop further charges and confirm in writing, but a reply is not guaranteed. What you can rely on is the delivery receipt: it shows the date Checkdomain received the request. If a charge posts after that date, quote the receipt with your copy of the letter.
