# Resend Verified Sender Request

## API Overview

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.

## Operation overview

```json
{"path":"https://api.sendgrid.com/v3/verified_senders/resend/{id}","method":"post","servers":[{"url":"https://api.sendgrid.com","description":"for global users and subusers"},{"url":"https://api.eu.sendgrid.com","description":"for EU regional subusers"}]}
```

**This endpoint allows you to resend a verification email to a specified Sender Identity**.

Passing the `id` assigned to a Sender Identity to this endpoint will resend a verification email to the `from_address` associated with the Sender Identity. This can be useful if someone loses their verification email or needs to have it resent for any other reason.

You can retrieve the IDs associated with Sender Identities by passing a "Get All Verified Senders" endpoint.
