Message Redaction is a feature offered by Twilio that allows developers to redact sensitive information from messages and phone numbers in their applications, providing an additional layer of customer privacy. This feature is now generally available and can be enabled on a per-message or account-level basis, with options for redacting both message body and phone number content. By using Message Redaction, organizations can ensure that sensitive communications are protected, while also meeting the needs of developers building novel projects to support critical experiences.
