Resubscribe with Zoho Campaigns

Hi,

I am new to Zoho Campaigns and sent a campaign to a contact list with only my email address. I wanted to see what the footer links did, so clicked unsubscribe and now can't include my email address into any more campaigns. I don't have a sign up form on my website to resubscribe and can't find how to resubscribe anywhere else. Can you help?
