# Sender Verification

The Sender Verification API exposes multiple endpoints that allow you to programmatically manage the [Sender Identities](/docs/sendgrid/for-developers/sending-email/sender-identity/) that are authorized to send email for your account. You can also manage Sender Identities in the SendGrid app by selecting [**Sender Authentication** under **Settings** in the navigation bar](https://app.sendgrid.com/settings/sender_auth). For full app instructions, see [Sender Verification](/docs/sendgrid/ui/sending-email/sender-verification/).

The Sender Verification API provides a RESTful interface for creating new Sender Identities, retrieving a list of existing Sender Identities, checking the status of a Sender Identity, updating a Sender Identity, and deleting a Sender Identity.

This API offers additional endpoints to check for domains known to implement DMARC, and resend verification emails to Sender Identities that have yet to complete the verification process.
