Duplicate Emails Sent on Cron Job (3-8 duplicates)

Hi,

We're experiencing multiple email notifications being sent to each user as a result of a new blog post. Some users have received 4 or up to 8 additional notifications.

I see the issue mentioned in forums here but no solution is particularly specified. If you are fixing on a case-by-case basis, please find my information below.

Help is greatly appreciated.
