# Limiting message parts

Would you rather avoid longer messages altogether? Specify whether or not a message should dispatch with a maximum number of message parts. Using the `max_number_of_message_parts` parameter, you can clarify a maximum number of message parts per batch.

It's also an option to configure a *default* `max_number_of_message_parts` at the account level. Contact your account manager to set a default maximum.

- If a message is split into more parts than `max_number_of_message_parts`, it won't be delivered. The status code will display a `411` error.
- If the `max_number_of_message_parts` parameter is specified when creating a batch, it will override the default value configured by your account manager.
- When the `max_number_of_message_parts` parameter is set or the default value is configured, the `number_of_message_parts` parameter will be included in the recipient delivery report.
