Boyum Print and Delivery send email with conditions

Hi Experts,

Is there anyway to send email as draft where customer account balance is more than 2,000. I have tried report action and sql condtions to check but can't achieve yet.

For example,

if due amount >2000 then save as draft email

if due amount <2000 then direct send email

The parameters is all customers.

Let me know if there any solution for this
