I need to extract Subscriber details and the List details they are on.
My below query is working but how can I narrow it to see who has signed up on the website in 2017 and has never been sent an email?
select l.ListID, l.ListName, l.EmailAddress, l.AddMethod,l.Addedby, l.CreatedDate, a.first_name_o, a.last_name_o, l.DateUnsubscribed, l.Status,a.job_title_o, a.library_type_o, S.EventDate
from ent._EnterpriseAttribute a
LEFT join _ListSubscribers l on a._SubscriberID = l.SubscriberID
LEFT JOIN _Sent S on a._SubscriberID = S.SubscriberID
where ListName <> 'All Subscribers'
