The Email Delay Service in SendGuard for Outlook provides the valuable benefit of allowing users to schedule email delivery at a later time. This feature is particularly useful for ensuring that emails are sent at the most opportune moments, whether it's to accommodate different time zones, schedule follow-ups, or maintain control over communication during non-business hours.

Our use case is limited to the delay feature and it works as expected. No Cons.
