How to cancel 123Energie by mail
Collect the details you need
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 123Energie has on file.
Prepare the letter
Postbye drafts the request in German, the language of Germany, with “Betreff: Kündigungsanfrage – [your name]” as the subject line. It asks 123Energie to close the subscription, stop billing and confirm in writing.
Mail it with tracking
Take the letter to the post office and ask for certified delivery to 67059 Ludwigshafen am Rhein. Keep the tracking number it gives you.
File the delivery record
Delivery confirmation is your evidence that 123Energie was asked. Watch the next statement or two for any further 123Energie charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel 123Energie, 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.
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.
