# 30615: Message couldn't be delivered

Log Type: APPLICATION

Log Level: ERROR

## Description

Twilio returns this error when local regulations prevent delivery to the recipient at the time you attempted to send the message. This most commonly affects non-essential messaging, such as marketing or promotional traffic, during restricted local quiet hours.

### Possible causes

* You attempted to send a non-essential message during the recipient's local quiet hours.
* The message content or use case was treated as marketing, promotional, or other non-essential traffic.
* The recipient is in a location with stricter quiet hours requirements than the standard 9:00 PM to 8:00 AM window.
* Quiet hours were evaluated using the recipient's local time, based on location information available for that recipient.

### Possible solutions

* Send non-essential traffic only during permitted local hours for the recipient.
* Review the message use case and make sure essential traffic is identified correctly with `messageIntent` when you use Compliance Toolkit.
* Improve recipient location accuracy so quiet hours are evaluated correctly for each recipient.
* Schedule the message for an allowed delivery time by using Message Scheduling.
* If you continue to see this error for traffic that should be allowed, collect at least three recent Message SIDs that returned 30615 and contact Support.
