As a Marketer who works with a Sales Team who would like to follow up with prospects/customers when they view pages on my website.
I use web tracking so I can use the Web Event trigger no problem, but unlike Acquisition Builder and Data Journeys, there is no "Send Notification" action available for Contact Journeys, where you can set a list of email address that would receive a customized message when a contact has arrived at that step in the journey.
The current workaround is as a customer, I would have to use the HTTP Post step to trigger an email solution I build and host myself, but this requires dev and hosting that I may not have access to.
