How to cancel Perfect Diary by mail
Note your account details
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 Perfect Diary is only as good as the details it quotes.
Draft the request
Postbye writes the letter in Chinese from our Chinese template, because Perfect Diary's address is in China. It opens with the subject line “主题：取消请求 – [your name]” and asks Perfect Diary to end the subscription, stop all further charges and confirm in writing.
Post it with proof of delivery
Send it certified to Guangzhou, China, copying the address from the next section letter for letter, and keep the receipt slip.
Save the tracking record
It shows the date Perfect Diary received your letter. Check your next statement: no Perfect Diary charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Every address we hold for Perfect Diary, with the envelope wording
Before you cancel Perfect Diary, check these
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
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.
