# New API endpoints introduced to manage blocked domains

Three new api endpoints have been introduced to manage blocked domains:

1. **[Add a domain](https://developers.sendinblue.com/reference#blocknewdomain)** to the list of blocked domains
2. **[Delete a domain](https://developers.sendinblue.com/reference#deleteblockeddomain)** from the list of blocked domains
3. **[Get the list](https://developers.sendinblue.com/reference#getblockeddomains)** of blocked domains

By adding a blocked domain in the transactional platform you ensure in the future any of your messages will not be sent to recipients under that address.\
*E.g: @blocked-domain.com*
