After a broadcast has been scheduled, you'll notice that the email becomes a read-only document. However, you may have the need to perform edits to it even after it's been scheduled.
Here's the message you'll see after a broadcast has been scheduled.
To unschedule a broadcast, go to the Settings tab of the individual broadcast and click Unschedule & Return to Draft.
Unscheduling a broadcast allows you to make any edits to the broadcast's content, settings, and scheduling.
When does it become too late to unschedule a broadcast email?
When a broadcast email begins its delivery, the option to unschedule it will no longer be accessible to you. If you've scheduled the broadcast to send immediately, there will only be a small window of opportunity to unschedule it before it begins to send.
When scheduled for a later date, broadcast delivery will be determined by time zone. Depending on this factor, your ability to unschedule a broadcast can vary.
A broadcast scheduled in the time zone of your account should be unscheduled at least 45 minutes prior to its scheduled delivery time if possible. This will ensure that no emails begin to render.
Additionally, any broadcast that is scheduled in your subscribers' local time zones will have the potential to begin delivering the email many hours before your own local time zone enters the queue to receive it.
You'll see the following message when you schedule a broadcast for delivery in your subscribers' local time zones.
To avoid unwanted email deliveries, we recommend keeping close attention to those broadcasts in your account which are scheduled for delivery in your subscribers' local time zones.
It's important to note, however, that Drip may begin to process the delivery queue of a broadcast email up to 24 hours before its scheduled delivery, no matter the time zone. This is to ensure that the broadcast is not delayed, especially when sent to a larger recipient list.
