How to cancel Cloudflare by mail
Collect the details you need
Start with the account email, the domain or server name and the invoice number of the plan being cancelled, so the request to Cloudflare names the right account the first time.
Set out the request
Ask Cloudflare to cancel the account, stop all further charges and confirm in writing. Postbye prepares the letter from our English template, with the subject line “Subject: Cancellation Request – [your name]”.
Post it with proof of delivery
Send it certified to London, United Kingdom, copying the address from the next section letter for letter, and keep the receipt slip.
File the delivery record
Keep the tracking record with your copy of the letter. If Cloudflare 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.

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.
