If you are on the Unlimited Plan, you can cancel at any time. If you are on the Pay Per Email Plan, there is no need to cancel because it is a pay-as-you-go plan.
To cancel:
- Choose Direct Mail > Direct Mail Account from the menu bar at the top of your screen
- Find the section titled Billing Plan and click Change
- Choose End monthly billing… and follow the on-screen instructions
After cancelling, you can still use Direct Mail, but will not be able to send email campaigns unless you purchase email credits or subscribe to a monthly plan.
If you purchased your Unlimited Plan using the App Store, then any changes to the plan, including cancellation, must be done via the App Store.
