blog emails

Hello, recently i had an issue where easyblog was sending multiple emails to each user. I posted here and kindly someone from your team went in and changed the setting "send emails on page load" to No. My question is do my subscribers now get emails about a New Blog Post or do i need to create a daily cron. I really want them to get notifications every-time i post a new blog. I am just not really sure what this setting does.
thanks in advance
