I want to pull each day my new leads

Do you just want a list of them?

You'll need to help us by defining what a "new lead" is.

Is it a lead that was created, or a lead that reached a certain score or what?

If I understand your question correctly, you would want to use Get Lead Activities with an activity Type Id of 12 (New Lead).

If you want to see the leads that were most recently created  do the following.

1. Go to Lead Database / System Smart Lists / All Leads

You need to create a new view

2. Create a new view: Latest leads

In hidden columns search for 'created' and add it to visible columns.

3. Click on view again. And select your 'Latest Leads' view.

4. Go to your Created column and click on it.

Select ascending or descending .

You will be able to see the leads that were most recently created.

Hope this helps.
