If a user needs to cancel or pause their Stamps.com subscription, they can do so at any time. Stamps.com typically allows users to manage their accounts through the account settings section on their website. When canceling a subscription, any unused postage or services may be forfeited, so it is wise for users to ensure that they have used what they need before canceling.

Users should also take note that any changes to the subscription status may take effect at the end of the current billing cycle, so users can review their billing information and account settings for any important details.
