You can easily filter your members in the system to continue your communication with your members in debt/ out of debt in this direction.
In your Raklet account, you can separate your Contacts by Membership-Balance filter.
To see your members in debt, it is enough to choose Membership-Balance ‘smaller than’ 0.
To see your members out of debt, choose Membership-Balance ‘is’ or ‘greater than’ 0.
Filtered members are listed on the right side of the page. You can tag this list and send bulk e-mail to your recipients afterwards.
