# X_NOTIFY_FANOUT_TOO_WIDE

## Means

the audience is larger than one run may fan out to

## Typical cause

the resolved audience passed `maxRecipients` (default 500). One step per recipient is what makes a provider blip re-send one address rather than all of them, and a step is a durable row — so there is a width past which this is the wrong shape entirely. Refused with both numbers rather than degraded silently

## Fix

deliver through a `bulkChannel()` on `notifier("<name>")`, which sends one payload for every recipient, or page the audience with `backfill()` from `@ultimat3/jobs`
