Can I cancel a newsletter send or prevent a sent message from being read?

You can cancel a newsletter send only for those recipients who have not yet received the message. In practice, for small sends, there is usually not enough time to cancel.

Follow these steps:

1. Open the Reports section from the left-hand menu.

2. Select the desired send by clicking its row.

3. Click Cancel in the top bar (this button is active only if the send is still in progress).

Unfortunately, you cannot prevent a newsletter that has already been sent from being read.
