Scrubbing Lead Lists

[Kisha Ulysse]

Hi all! So we are using a CRM called Insightly to manage our leads, and I'm trying to find out the best way to go about cleaning the list. Currently I am going through all of the addresses one by one to see if the property has sold so we can tag them and no longer market to them. Someone please tell me there's an easier way! I imagine we could use a VA to do it manually, but I'm wondering if there's some sort of integration or program we could use to get this done quickly. Thanks in advance for your help!!
