Remove contacts

Remove contacts

Hello,

We would like to import new contacts to create an email campaign, not to reach the maximum of 2500 contacts, we try to remove our old buddy lists, but this message:

You are not allowed to remove more contacts because you've already exceeded the maximum limit of deleting contacts for this organization. For further information, please contact our helpdesk to support@zohocampaigns.com.

How can we remove our listings?

Thank you for your help
