Hello @tri​ ,

How about tagging these users for some new tag, then use the following tag as an entry rule in the Series.

Let me know if this is what you are looking for.

Best,

Roy

Yeh, I did try but it's not working. The thing is, the first trigger is to send an email when 'New lead via signup'. But these leads are already in our contact list. I've removed this rule and tagged people but they still don't enter the Serie.

Could you add a screenshot of your filter? Maybe we can find a filter that is responsible for excluding the tags

Sure please see below.

This is the list that intercom said would enter the Series

ie. 'If you set this Series live, they would enter it, as well as new people that start to match your rules.'

I guess it's because of the "when to send" trigger. The users you tag retroactively probably won't trigger as new leads. But you should still be able to add them to the audience like Roy suggested.
