 ### Dealing With Network Failures
 
-An `HTTP 2xx` status code response from Sentry is considered a successful send. It's important to note that retry is only considered in the event of a network failure. For example:
+When SDKs receive an `HTTP 2xx` status code response from Sentry, they **MUST** consider it as a successful send. If Sentry returns an `HTTP 4xx` (excluding `HTTP 429`) or `HTTP 5xx` status code, SDKs **MUST** discard the envelope and record a [client report](/sdk/telemetry/client-reports) with the discard reason `send_error`. For an `HTTP 429` response, SDKs **MUST NOT** record a client report to comply with the [rate limiting](/sdk/expected-features/rate-limiting/) rules, because the backend already records a client report for the rate limit. SDKs **MAY** retry sending the envelope when a network error occurs, such as:
 
 * Connection timeout
 * DSN resolution failure
 * Connection reset by peer
 
-Other failures, like those caused by processing the file in the SDK itself, the payload should be discarded since those are likely to end up on an endless retry.
-If the event reached Sentry and an HTTP response status code was received, even in the event of an `HTTP 500` status code, the event should be discarded.
+When other failures occur, like those caused by processing the file in the SDK itself, SDKs **MUST** discard the envelope and record a [client report](/sdk/telemetry/client-reports) with the discard reason `internal_sdk_error`. Otherwise, the SDK might end up in an endless retry loop.
