How to cancel Silk And Sonder by mail
Start with your account details
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Silk And Sonder can only act on a request it can match to an account.
Write the cancellation request
Ask Silk And Sonder 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 – Silk And Sonder”.
Post the letter
Post it by certified mail to Silk And Sonder in San Francisco, United States, using the exact address below, and note the tracking number.
Save the tracking record
File the receipt with the letter. A Silk And Sonder charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Silk And Sonder, check these
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- 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.
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.
