How to prepare this report (NEW CONTACTS in the Segment) - any ideas?

Good morning,

We want to receive the daily report with the information regarding who has been added to the segment (new contacts). We did try data export tool, but instead of information with new contacts, we receive reports with contacts who had been in the segment earlier and most importantly didn't submit the form (we want to receive report with the information of new contacts, who submitted the form).

It turns out, that “only records changed since last run” option means the contacts that made some change and not that we interpreted it the contacts which was added to the segment that day.
