This has come up often enough that it merits a post. Reminders of sorts can be set up a few ways in ServiceNow. This is just the pros and cons of each.

So there's a few ways I know of doing this;

• Scheduled Report
• SLA Notifications
• Scheduled Job (much like incident auto close)
• Scheduled Events

Each of these have their pro's and con's, lets get into it.

Scheduled Report

Probably the easiest to set up as it just requires a report, and a scheduled report.

Pro	Con
Only requires Report, and Scheduled Report	Only occurs at the frequency it scheduled
No coding required	Less configurable
No email template to set up	Email is set based on report sharing

SLA Notifications

Pro	Con
No coding required	Only occurs at the frequency it scheduled
	Specific to tasks

Scheduled Job

Pro	Con
Only Requires Scheduled Job, Event, Notification	Only occurs at the frequency it scheduled
Very configurable due to coding	Requires coding

Scheduled Events

Pro	Con
Triggers when it's supposed to	Requires Event, Notification, Business Rules, and possibly it's own event queue
Very configurable	Requires coding
	Requires managing the scheduled events if the date/time changes
