# Receiving observability

> Monitor received message volume, security check results, and top recipients across your receiving domains.

The **Receiving** tab of the [observability dashboard](/docs/guides/observability) gives you visibility into the messages received across your receiving-enabled domains.

## Summary cards

Key metrics at a glance: total messages received, flagged messages, and messages sent from inboxes over the selected period.

## Message volume

A time-series chart showing the number of messages received over time. Use this chart to spot traffic patterns or unexpected spikes.

## Messages by domain

A breakdown of received messages by sending domain, so you can see which domains are generating the most inbound traffic.

## Security checks

A chart showing the results of security checks (SPF, DKIM, spam verdict, virus scan) for received messages. Use this to monitor the health of your receiving pipeline and identify potential abuse.

## Top recipients

A ranking of the most active inboxes by received message volume. Use this to identify high-traffic addresses and detect unexpected activity on infrequently-used inboxes.
