How to cancel Kagi by mail
Start with 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 Kagi is the easiest one to set aside.
Set out the request
Ask Kagi 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: Subscription termination – Kagi”.
Send the letter by certified mail
Send the letter to the San Francisco mailing address shown below by certified mail. Keep the tracking number safe.
Keep the delivery receipt
The receipt dates your request. Look at your next statement for any Kagi charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Kagi cancellation letter goes
Kagi lists Market Street 548, San Francisco 94104 as its mailing address.
ZIP code 94104 places the address in San Francisco County, in the United States.
Your details go in a block headed by Name, Address and E-mail, and the opening line is “To Whom It May Concern,”.

Before you cancel Kagi, 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
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
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.
