How to setup a Smart list for leads who have not opened any of our emails in past more than 6 months?

Hi, 

I am creating a smart list to see our inactive leads for past 6 months and for more than 6 months. So for 6 months it's very clear but what should I put in Date of Activity field for more than 6 months in past?

Thanks

Mohit

Open email is retained for 25 months according to data retention policy docs.

Wouldn't you just use this for inactives in past 6 months and use 25 months for everyone else?

This is where you'd use the In Past Before operator.
