Quanda allows 35 active e-mail campaigns, that is campaigns in the "ready to use" state, which is shown by a tick in a green circle.
If you reach that number, you have to "End" or possibly "Pause" older campaigns. You end a campaign simply in the campaign overview, in the Actions section under the square icon in a grey circle.
We recommend "ending" several of them at once, so that you can send new campaigns without having to think about closing an older one every time.
