How to cancel Eversource by mail
Collect the details you need
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to Eversource is only as good as the details it quotes.
Prepare the letter
The letter asks Eversource to end the account, stop every future charge and confirm it in writing, under the subject line “Subject: Subscription termination – Eversource”. Postbye fills it in from our English template.
Post the letter
Address the envelope to Eversource, Westwood, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Keep the delivery receipt
Keep the tracking record with your copy of the letter. If Eversource 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 Eversource, 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
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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
