Senders are authorised addresses used to send email messages from your Brevo account. Create, delete, update, and retrieve senders through the endpoints in [API Reference > Senders](/reference/create-sender).

## Requirements

To use the Senders and Domains endpoints, you need to:

1. Create a Brevo account.
2. Log in to your Brevo account.
3. Use an API key. See [Guides > Welcome](/docs/how-it-works) to retrieve your API key from the Brevo developers dashboard.

#### Domain Authentication

Verify the sender's email to confirm its authenticity, and authenticate the domain so the sender appears as verified. Learn more about the verification process **[here](https://www.google.com/search?client=safari\&rls=en\&q=sendinblue+validate+sender\&ie=UTF-8\&oe=UTF-8)**.
