How to cancel Just Energy by mail
Get your account details together
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 Just Energy has on file.
Set out the request
Postbye turns the request into a finished English letter headed “Subject: Subscription termination – Just Energy”: close the Just Energy account, stop every charge and reply in writing.
Send it by certified mail
Use certified mail for the 77056 Houston address in the next section, so the post office records the delivery. Write down the tracking number.
Keep the delivery receipt
It shows the date Just Energy received your letter. Check your next statement: no Just Energy charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Just Energy cancellation letter goes
Just Energy lists 5251 Westheimer Rd, Suite 1000, Houston, TX 77056 as its mailing address.
ZIP code 77056 is in Texas, so the letter stays inside the United States postal system.
Your details go in a block headed by Name, Address and E-mail, and the opening line is “To Whom It May Concern,”.

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