+
+To provide consistent performance and reliability at scale, Segment enforces default use limits for Linked Events.
+
+## Usage limits
+Linked Events provide you with the flexibility to enrich unlimited events in downstream destinations. This means you won't encounter any limitations or pauses in service related to the number of Linked Events enrichments.
+
+Segment measures Linked Events limits based on entities and entity rows. 
+* **Entities:** The warehouse tables that are declared in the Data Graph with the `enrichment_enabled = true` property. 
+* **Entity rows**: The total number of rows synced to Segment cache across all enrichment entities within a Segment workspace at any given time.
+
+To see how many entities and entity rows you’re using with Linked Events, navigate to **Settings > Usage & billing** and select the **Linked Events** tab.
+

+### Special cases
+* If you have a non-standard or high volume usage plan, you may have unique Linked Events limits or custom pricing.
+* If you're on the trial version of Linked Events, you won't be able to add more than 1 million entity row syncs. Reach out to your Customer Success representative to upgrade to the Linked Events paid tier.
+* If you're using the paid version of Linked Events, and you reach your entity row limit before the end of your billing period, your syncs won't automatically pause to avoid disruptions to your business. You may be billed for overages in cases of significant excess usage. If you consistently require a higher limit, please contact your sales representative to upgrade your plan with a custom limit.
