Every senior fulfiller I have ever shadowed has a single Outlook rule: “ServiceNow -> archive on receive.” The platform has trained them to ignore notifications because so many are duplicate, irrelevant, or fired by an automation that nobody remembers writing. The fix is a deduplication and digest layer — and it does not exist out of the box.
The pattern: queue then dispatch
Replace direct sys_email insertion with a queue table you control. A scheduled job dispatches with deduplication, batching, and digest logic.
Table: u_notification_queue
Columns:
recipient (user)
subject_key (string, used for dedup)
source_table
source_sys_id
payload (json)
queued_at
dispatched_at
collapsed_count (integer, default 1)
subject_key is the dedup key. Two messages with the same key within the dedup window collapse into one with collapsed_count incremented.
Dedup windows by message type
- Assignment changed — 60 second window
- Comment added — 5 minute window
- State changed — 60 second window
- Approval requested — never collapse
Tune per recipient role if you have heavy fulfillers vs light approvers.
The dispatch script
var Dispatcher = Class.create();
Dispatcher.prototype = {
dispatch: function() {
var ga = new GlideAggregate('u_notification_queue');
ga.addNullQuery('dispatched_at');
ga.addAggregate('COUNT');
ga.addAggregate('MAX', 'queued_at');
ga.groupBy('recipient');
ga.groupBy('subject_key');
ga.query();
while (ga.next()) {
// emit one email per (recipient, subject_key) bucket
}
},
type: 'Dispatcher'
};
Daily digest for low-priority types
Comment notifications and watchlist updates should default to a daily digest, opt-in to immediate. The platform’s preference center supports this — most teams never wire it.
Quiet hours per user
Pull cmn_schedule for the user’s timezone and suppress non-critical notifications between 8pm and 7am local time. Critical (P1, on-call page) bypass.
Measure the impact
Track average notifications per fulfiller per day before and after. A typical reduction is 50-65%. The metric that actually matters is fulfiller satisfaction in the next pulse survey.
What to do this week
Audit the top 5 notification rules by send volume in the last 7 days. Pick the noisiest one and route it through a deduplication wrapper for a pilot group. Two weeks later, expand to the whole org with the win story attached.
