How to cancel Erth Labs by mail
Gather 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 Erth Labs is only as good as the details it quotes.
Write the cancellation request
Ask Erth Labs 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 – Erth Labs”.
Mail it with tracking
Post it by certified mail to Erth Labs in Pasadena, United States, using the exact address below, and note the tracking number.
Save the tracking record
File the receipt with the letter. A Erth Labs charge dated after delivery is the one to dispute, and these two documents are what you quote.

Before you cancel Erth Labs, check these
- 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.
- Check your next statement: no charge should appear after the cancellation date.

How cancelling by mail works
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
