Hello Gaurav,
Despite Quickbase formula language not being all that helpful compared to modern formula languages, there is another approach. You can add some javascript to this page using Dan Dieboldt's image onload technique. This Javascript would be able to read and parse the text entered and submit new child records for those emails. Notifications would therefore be driven in this solution from this child table.
Alternatively, you can populate user-list fields to accomplish the same thing.
Alternatively once more, you can have javascript send these emails instead.
There are a lot of options, none of them rely on native Quickbase. I hope this has been helpful. Please let me know if you need help with any of this.
Best regards,
David Maskasky
