Scheduled notifications in Sales Cloud
Team,
Have a requirement to send reminder notification email to assignee (scheduled notifications in every 15 mins) when a service request is assigned and not attended.
Below options were explored :
1)Service Offering
2)Groovy notification triggers
3)Scheduled groovy object function
4)Workflow approvals and notifications ( Didn't find any related to service request)
What is the best option to perform this .
TIA
