How to have an intro text ONLY when there are new posts

I use MailPoet to send “Post Notifications” emails to subscribers.

My email is composed of various sections, and it has a structure similar to this:

1. welcome
2. intro text for section 1
3. new posts for post type A
4. intro text for section 2
5. new posts for post type B
6. etc.

As expected, MailPoet does NOT publish anything in #3 and/or #5 if there’s nothing new. This is great and what I want.

However, I would like the intro text at #2 and/or #4 to also not be visible if there’s nothing new in #3 and/or #5.

Is it a feature that we might hope to see in the near future? Or something that can be achieved today?

Thanks
