# Deprecated Resources

On April 5th 2018 the API endpoints used for retrieving stats were revamped in a major way. Stats for any account migrated or created after April 5th 2018 can be retrieved with the newly created endpoints.

The main improvements of the new system include:

- Streamlined API endpoints, combining several legacy resources into one to ease the retrieval of key performance stats
- Detailed stats on clicked links, including number of unique and total clicks, URL position etc.
- Statistics based on Mailbox providers, which allow you to easily identify issues with deliverability / engagement based on the recipients' mailbox providers
