# The Legacy Sender Identities API is deprecated

SendGrid API deprecated /v3/senders* without giving a shutdown date yet.

The Legacy Sender Identities API has been deprecated without a shutdown date. This deprecation affects all requests to the /v3/senders* endpoints, which cover the obsolete legacy marketing campaigns feature. Once permanently removed, calls to these endpoints will fail.

## What to use instead

Manage senders with the Marketing Campaigns Senders API (/v3/marketing/senders). The new Marketing Campaigns keeps its own contacts, lists, and senders, so moving requires migrating your data rather than just updating endpoint calls.

The new Marketing Campaigns keeps its own contacts, lists and senders; moving means migrating them, not only the calls.
