How to cancel Simplifi by mail
Get your account details together
Put the account email, the last four digits of the linked bank account or card and the membership tier in front of you before you write: the request to Simplifi is only as good as the details it quotes.
Write the cancellation request
Your Postbye letter to Simplifi asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Subscription termination – Simplifi”. It comes from our English template.
Post the letter
Use certified mail for the 94025 Menlo Park address in the next section, so the post office records the delivery. Write down the tracking number.
File the delivery record
File the receipt with the letter. A Simplifi 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.
Where your Simplifi cancellation letter goes
Written requests to Simplifi go to Haven Avenue 3760, Menlo Park 94025.
ZIP code 94025 places the address in California, 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,”.

Every address we hold for Simplifi, with the envelope wording
Before you cancel Simplifi, check these
- Settle any outstanding balance first. Closing a membership does not clear what you owe.
- Ask for the direct debit or card authorisation to be ended, not only the membership.
- Investment and credit-builder products can have their own steps for closing the underlying account.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a finance or credit subscription
Finance and credit apps bill a membership fee through a linked account, so the request has to end the membership and the authorisation to take payments.
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.
