# Senders

US, Canadian, and EU regulations require specifying a sender for email messages. This identifies where each email message you send originates.

Before you can edit or use your sender identity email address to schedule a Single Send or set an Automation, you must verify that email address. If you have an [authenticated domain][] and your sender email address matches that domain exactly, Twilio verifies your sender identity.

## What makes email sender metadata important

Accurate and trustworthy sender metadata ensure the success of your campaigns and maintaining a positive sender reputation. To build trust with your recipients and the intermediate checkpoints like spam filters and ISPs, complete the following tasks as you add senders:

* Configure your `From` name and email address for your sender.
* Validate that your sender metadata complies with local, regional, and national email regulations in both the sender's and recipient's locations.
* Set up your company's address and contact details for transparency and trustworthiness.

## Add a sender

You may create up to 100 unique senders.

To add a Sender:

1. Log in to the Twilio SendGrid console.
2. Go to **Marketing** > **Senders**. The **Sender Management** page appears.
3. Click **Create New Sender**. The **Add a Sender** panel appears.
4. Complete the fields in the panel.

   | Field               | Expected value                                                                                                                                                                                    |

   | **From name**       | The name of the person or organization you want to send the email message.                                                                                                                        |
   | **From email**      | The email address of the person or organization you want to send the email message.                                                                                                               |
   | **Reply to email**  | The email address of the person, organization, or role to which you want replies sent.                                                                                                            |
   | **Company address** | The physical location of the organization on whose behalf you're sending email messages. This includes the **Company Address Line 2**, **City**, **State**, **Zip Code**, and **Country** fields. |
   | **Nickname**        | A human-readable label that identifies this sender for your reference. Twilio doesn't display this field to recipients.                                                                           |
5. Click **Save**.
6. Check the inbox of the email address that you entered.
7. To verify the Sender email, click the link in the email.
8. If you need to resend the verification email, click the ⋮ menu then **Resend Verification**.

Once you schedule a Single Send or set an Automation, you can't delete the sender identity associated with that Single Send or Automation.
