Email Entries on a promotion sends every tribe with entries a report of their own entrants, as a PDF attachment, with a message you write.
Sending it
The dialog is titled Email Entries to Tribes and asks for a Message, which is required. Press Send and you are told Tribes have been notified. The email arrives with the subject Promotion Entries Report and an entries.pdf attached.
It goes to everybody
What to write
The message is the whole point — the PDF is just a list. Say what the competition was, what you want the tribe to do with the names, and by when. "Attached are the people who entered our winter competition at your store. Please call each one within a week and offer them a quote" produces follow-up; a bare "here are your entries" does not.
It is a snapshot
The PDF captures the entries as they stand when you send. Entries arriving afterwards are not in it, so send it once the competition has closed — or send again later, which produces a fresh report.
The alternative
If your tribes use Gorilla Dash daily, switching on Show entries to tribes is better than emailing a PDF — they see entries live, and can record a follow-up status you can then report on. Use the email for tribes that will not log in.
