General delivery
"General delivery" notifications are visible by everyone in your VSys installation through the "Notification window in VSys One". They appear in a block on the VSys One home screen. Use these if your organization is small and you're not using VSys Security, or for notifications that everyone should see.
Automatic recipients
For "Automatic recipients", VSys attempts to determine who in VSys should be notified based on the notification. For example, a notification about Self-cancelled interview would be sent to the interviewer assigned to that interview (if possible). Some notification events like Indices need rebuilding can't be used with this subscriber.
Primary supervisor
"Primary supervisor" notifications are sent to the primary supervisor for the related person. The primary supervisor must first be defined in the person's profile in the Relationships panel. Notification events not associated with people, for example, Standalone E-mail Robot not running, are not available for this subscriber.
"Automatic recipient" and "Primary supervisor" are considered virtual subscribers by VSys. This means that they're not associated with a real person and VSys attempts to match the appropriate recipient based on what it knows about the event. Subscriptions for these subscribers can optionally be flagged to not be sent to people who have their own explicit subscriptions for the same types of events.
Specific person
For these notifications you're selecting an individual person in VSys - usually a staff member, supervisor, etc. - and assigning notification events to him. VSys will use the contact information in that person's profile to determine where to send the notification.
Referenced person
Only certain types of notifications are eligible to be used for this virtual subscriber. For each notification, VSys will determine who the referenced person is. For example, an assignment's referenced person would be the volunteer, and a training's referenced person would be the student. You can use this virtual subscriber to define, for example, a notification that is sent to everyone in a training course ten days before the course begins.
Social media
These notifications are posted to a single social media profile. Only anniversaries, awards, birthdays and slots needing volunteers can be used for social media subscriptions. Any notification which references a specific person will not be delivered if that person's contact flags include "No social media".
Others in job slot
Applicable only to notifications based around job slots, these generate notifications to all of volunteers in the job slot. This is a virtual subscriber. (For cancelled assignments, they're not sent to the person whose assignment is cancelled.)
Others with job association
Only used for "Self-cancelled assignment" and "Slots needing volunteers", this generates notifications to other volunteers who have active job associations for the referenced job. You'd most commonly use these to notify volunteers who are eligible to replace the volunteer whose assignment is cancelled, or to find volunteers for the job slot that is still not filled. This is a virtual subscriber.
Recipients via subscription in VSys Security rights
Within a VSys Security user's security profile, that user can be linked to requested sites, requested departments and/or groups. Notifications for this virtual subscriber get sent to the VSys Security users who are linked to:
Notification relationship
Notifications generated for application forms can determine who to notify based on people with relationships to the Requested site and/or Requested department. This is a virtual subscriber.
Recipients via relationship to the referenced person's groups
This convoluted virtual subscriber generates notifications to the people who have a "Group notification contact" relationship to the groups of the person that the notification references. The "Recipients via relationship to the referenced person's groups" is deprecated in favor of the "Recipients via subscription in VSys Security rights" mechanism which is much more straightforward to use.
