Clearing Bounce List in Zoho Campaigns

We recently started experimenting with Zoho Campaigns, and we had a first campaign that went bad. We didn't realize we did not have an SPF record set up, so a lot of valid addresses got moved to the bounce list.

Now that we have figured out the problem, we would like to start over. Is there any way to clear the bounce list so that emails will go through to the addresses that bounced when we didn't have an SPF record configure?
