Hello @JasonC593 ,
Thank you for reaching out to us. You do have the ability to delete multiple emails at a time by checking off the check boxes next to them, from the campaigns page. However, all emails have to be in either a "Sent" or "Draft" status in order to be deleted. At this time, we also do not have a feature that allows the ability to unschedule more than one email at a time. The method you are using for that, is the only method. This is all really great feedback and I will be sure to submit these ideas as a feature request to our product team.
This should absolutley be a feature. Our company sometimes schedules every other day for an entire month, and if we need to make a change we have to spend so much time unscheduling each individual email, its ridiculous.
Thanks so much for your feedback! We encourage you to pass along this idea directly to our product teams. You can post it in the feedback section.
