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

There's a four 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 requires a report, and a scheduled report.

Pro	Con
A Report, and Scheduled Report	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	Occurs at the frequency it scheduled
Specific to tasks

Scheduled Job

Pro	Con
Requires Scheduled Job, Event, Notification	Occurs at the frequency it scheduled
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
Configurable	Requires coding
Requires managing the scheduled events if the date/time changes

Scheduled Flow Trigger

Pro	Con
Access be delegated using Scoped App and Flow Designer content filtering	Delegates can reak havoc, shouldn't create them directly in prod.

Thansks @milligna!
