If you create a Direct Mail Campaign but need to cancel it, you can do so within 1 hour of the campaign being launched. If you are outside of the 1 hour time range, then unfortunately that campaign will not be able to stopped or cancelled.
If you are within that 1 hour range, you will need to navigate to the Help section of Real Mailers website. Once you are there, click the blue Chat icon in the bottom right hand corner and select the Cancel a Campaign option on the next screen.
From there, you will need to answer a few questions about the campaign and the cancellation will be processed.
