How to cancel TXU Energy by mail
Note your account details
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 TXU Energy has on file.
Prepare the letter
Your Postbye letter to TXU Energy asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Subscription termination – TXU Energy”. It comes from our English template.
Mail it with tracking
Use certified mail for the 75039 Irving address in the next section, so the post office records the delivery. Write down the tracking number.
Keep proof the letter arrived
Delivery confirmation is your evidence that TXU Energy was asked. Watch the next statement or two for any further TXU Energy charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel TXU Energy, check these
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- 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.
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.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
