Twilio SMS message and traffic storage

Twilio SMS and MMS messages, including message bodies and records, are kept in Twilio's cloud storage until a customer requests them be removed. Customers can request messages to be deleted at any time via an HTTP DELETE request.

Once an HTTP DELETE request is received, the corresponding message is removed from the customer facing repository that holds messages. Deleted messages can not be recovered. Message bodies may persist for up to 30 days after an HTTP DELETE request in our database backups.

Upcoming changes to message data retention on October 14, 2020

Starting October 14, the Message Logs in the Twilio Console and the Messages API Resource will display message records for up to 13 months after the message is created. With the exception of Twilio Programmable Chat and Conversations, this new data access policy will apply to all Messaging Channels - SMS, MMS, WhatsApp, etc. 

Message records older than 13 months will not be deleted from Twilio – all the data other than media attachments will remain accessible indefinitely through the new Bulk Export API (Beta released in April 2020) or from the Twilio Console under Programmable Messaging / Settings / Archives

Message media objects (e.g. MMS attachments) older than 13 months will be permanently deleted, starting October 14.

Message media objects are images, audio files, or other attachments that you have sent or received using MMS or WhatsApp Media messages.
