One issue is that the email notification will not be able to process a single field with multiple email addresses. It will only work for separate fields. I like to list the fields vertically for readability. Hence 150 ! formula fields to parse out the 1st, 2nd 3rd.. 150th,... email address from that combined text summary field.
You have think through rough if you want an EOTI App. (Everyone On The Internet). If the pipeline is doing the work then the app does not need to be EOTI. If you actually expose the app to EOTI directly then you need to think through how you prevent someone, say a disgruntled X-employee, from messing with you data.
