Hello,
from your description, I think it is optimal to create an automated python script, which will extract the needed data from your list based on your criteria and create a mailing list from it. I could build such a script for you so that you can use it in the future for similar tasks. It strongly depends on the kind of data format you have and on other details and your requirements. I am looking forward to chatting with you about the details, just contact me. I will deliver to your full satisfaction since I am new to Freelancer, I will be open for some refinements on the script after the completion. Just contact me, I am ready to start.
Best,
Anton Krashennikov
