Question : How bulk email works for whizbiz?
Let us first clear the bulk email feature
1. Suppose user A have a business posted on your website
2. Now user B , User C and User D contacted User A via the contact form on business details page
3. Bow user A will be able to see email ids of user B,C and D on that "To" input field.
4. If user A wants he can send email to all the users who contacted him at a time
There is another bulk email feature added for only the admin on version 1.5. Using this feature from admin panel > users > all users > bulk email then admin can send bulk email to all the registered users.
