How to cancel Heroku by mail
Find your account details
Start with the account email, the domain or server name and the invoice number of the plan being cancelled, so the request to Heroku names the right account the first time.
Prepare the letter
Your Postbye letter to Heroku asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Subscription termination – Heroku”. It comes from our English template.
Post it with proof of delivery
Mail the letter by certified mail to the San Francisco address in the next section, and keep the tracking number.
Save the tracking record
Keep the tracking record with your copy of the letter. If Heroku 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.
Where your Heroku cancellation letter goes
Heroku can be reached by post at Mission Street 415, 300, San Francisco 94105.
ZIP code 94105 places the address in California, in the United States.
The letter is addressed “To Whom It May Concern,” and its details block uses the labels Name, Address and E-mail.

Before you cancel Heroku, check these
- Download your data before the cancellation date. Servers are usually wiped soon after.
- If the domain moves to another host, transfer it first, then cancel the hosting.
- Domains, SSL certificates and backups can renew separately. List each service you want to stop.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a hosting or cloud-storage plan
Hosting and cloud plans are often prepaid for a term and renew with domains and add-ons on separate dates, so the request should list each service that should stop renewing.
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.
