How to cancel Honeywell by mail
Find your account details
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Honeywell is the easiest one to set aside.
Set out the request
Your Postbye letter to Honeywell asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Cancellation Request – [your name]”. It comes from our English template.
Send the letter by certified mail
Use certified mail for the 2113 North Ryde address in the next section, so the post office records the delivery. Write down the tracking number.
Hold on to the receipt
The receipt dates your request. Look at your next statement for any Honeywell charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Honeywell cancellation letter goes
Honeywell lists Richardson Place 2, 3, 2113 North Ryde, Australia as its mailing address.
Copy the postal code 2113 exactly: it is what routes the letter to New South Wales, Australia.
The letter is addressed “To Whom It May Concern,” and its details block uses the labels Account holder, Billing address on file and Email on file.

Before you cancel Honeywell, 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.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
