How to cancel TomoBoost by mail

  1. Find your account details

    Before writing, collect the name and email on the account and, if you have one, an account or customer number. TomoBoost can only act on a request it can match to an account.

  2. Draft the request

    Your Postbye letter to TomoBoost asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Subscription termination – TomoBoost”. It comes from our English template.

  3. Send it by certified mail

    Post it by certified mail to TomoBoost in San Francisco, United States, using the exact address below, and note the tracking number.

  4. Keep the proof of delivery

    Delivery confirmation is your evidence that TomoBoost was asked. Watch the next statement or two for any further TomoBoost charge.

  • 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.
  • Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.

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.

Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
