HI,
I'm publishing the report to a greater audience, with a link so that they can view in the browser. Without signing up. I would like to see if i can set an alert to a group of emails and blast out an email whenever there is an update.
Thanks!

"Without signing up", so I assume that you would use Publish to web or Embedding with non-Power BI users. For Publish to web, you shall note the limitations and data refresh(approximate one hour delay). For the latter, you'll need premium license.
As to "blast out an email whenever there is an update", if the update means republish/re-uploading a new pbix to replace the old one, there's no alert feature. However you could do the republish/re-uploading via programming way and blast out an email by coding yourself.
See a demo.
