You can now create live genre segments that will automatically update when a customer purchases a ticket for that specific genre. Below is how you can merge your pre-existing static genre segments with your new live segment, so that all of your contacts live in one place.
1) Create a live segment for each genre
On the left sidebar, click Segments> New Segment
Name the segment something like "Genre_Title Live" (e.g; Hip Hop Live)
Choose Live Segment as the segment type
Click +Add Filter
Under Categories, click Event Data > Purchased Ticket(s) > Purchased Tickets for Event Genre
Select the Hip Hop genre from the dropdown
Click Save Segment
2) Merge your pre-existing static genre segment with your newly created live segment
Again, on the segments page, click +New segment
Name the segment something like "Genre_Title Total" (e.g; Hip Hop Total)
Choose Live Segment as the segment type
Click +Add Filter
Under categories, click Popular Filters > Segment
Select the "Genre_Title Live" segment created in step 1) from the drop down
Click +Add Filter
Under categories, click Popular Filters > Segment
Select your pre-existing Hip Hop genre static segment from the drop down
Change the parameter from AND to OR, to ensure all contacts are merged
Click Save Segment
Now all of your subscribers who purchase tickets for that specific genre will automatically be added to this segment.
Continue this process for each of your remaining genres!
