In the Audience section, you can work on a segment that you have created.

If you modify the filters, you will have the option to create a new different segment, or modify the existing one.

At this point, we will have available users whose email and telephone number have any value. If you do not want to create a new segment, you must click on 'Save segment', and the new filters will be applied.

You can also send a campaign to this group of contacts.

Additionally, in the Segments section, you will be able to create a new segment and see the existing ones, as well as perform actions on them, including editing or deleting. You must press the three dots under the Actions column.
