TrackingConfigurationOverrides
An object that overrides, for a single email sending request, the engagement tracking settings that would otherwise apply. Use these overrides to turn open tracking or click tracking on or off for an individual message, for example to suppress tracking in a transactional message that you send from an account or a configuration set that has tracking enabled.
Without an override, engagement tracking is determined by your account-level EngagementMetrics setting, which you configure using the PutAccountVdmAttributes operation, by the EngagementMetrics setting of the configuration set that the message uses, which you configure using the PutConfigurationSetVdmOptions operation, and by whether that configuration set has an event destination whose MatchingEventTypes include the OPEN or CLICK event types.
For more information about tracking open and click events, see the Amazon SES Developer Guide.
