How to cancel Deine Warmeenergie by mail
Find your account details
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Deine Warmeenergie can only act on a request it can match to an account.
Write your request
Postbye drafts the request in German, the language of Germany, with “Betreff: Kündigungsanfrage – [your name]” as the subject line. It asks Deine Warmeenergie to close the subscription, stop billing and confirm in writing.
Send the letter by certified mail
Take the letter to the post office and ask for certified delivery to 45128 Essen. Keep the tracking number it gives you.
Hold on to the receipt
Keep the tracking record with your copy of the letter. If Deine Warmeenergie 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 Deine Warmeenergie, 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.
