# Sender and tracking domains > Send email from your own domain, and use your own host for email and website tracking. Source: https://help.clockworkcrm.com/admin/domains Last updated: 2026-09-28 Only administrators can manage sender and tracking domains. ## Sender domains Found under **Administrator Tools → Sender Domains**: a sender domain is a domain you've given Clockwork CRM permission to send emails from. Used in things like Automations, Bulk Email Shots and Marketing Sequences. We include a sender domain by default that's associated to your subdomain, so you don't need to set it up to get started with sending emails. ![The sender domain list](https://clockworkcrm.blob.core.windows.net/public-internal/docs/admin/admin-sender-domains.png?v=ff8de19e) Each domain is listed with its **Name**, **Status**, **Last Modified** date, **Last Modified By** and **Created By**. **Search for domains...** filters the list. | Status | What it means | |---|---| | **Pending** | Waiting for you to add the DNS records and verify the domain | | **Verified** | The domain is verified. You can send email from it | | **Rejected** | The domain was not verified in time | ### Adding a sender domain Adding DNS records needs access to your domain's DNS settings. If you do not manage the domain, pass these steps to whoever does. 1. Select **Add Sender Domain**. 2. Enter the **Domain Name**. This is the root domain, such as clockworkcrm.com, without "https://". 3. Select **Next**. Clockwork CRM shows the CNAME records to add to the domain's DNS. Each record has a **Record Name** and a **Record Value**, with a button to copy each one. 4. Add the records at your DNS provider. You have 72 hours to add them. 5. Select **Verify**. When the records are found, the status changes to **Verified**. If they are not found yet, it stays **Pending**, and you can verify again later. To see the records again, open the actions on the domain's row and select **View Verification Information**. For a pending domain, this also has the **Verify** button. A domain that was not verified in time is **Rejected**. To try again, add it again. ### Sender addresses A sender address is an email address on one of your sender domains, such as support@clockworkcrm.com. You'll be adding the individual addresses e.g. **support** in this case. To see a domain's addresses, double-click its row, or open the actions on its row and select **Manage Addresses**. **Sender Addresses** lists each address with its **Name**, **Address**, **Last Modified** date, **Last Modified By** and **Created By**. **Search for addresses...** filters the list. Select **Add Sender Address** to add one. | Field | What it does | |---|---| | **Name** | The name recipients see the email come from, such as "Jane Smith". 2 to 80 characters. Required | | **Address** | The part of the address before the @, such as "jane.smith". Use lower-case letters, numbers and . _ % + - only. The domain is added for you. Required | | **Reply-to name** | The name shown with the reply-to address, such as "Support Team". Up to 80 characters. Optional | | **Reply-to address** | Where replies to emails from this address go. Leave it blank and replies go to the sending address. Optional | | **Signature Content (Html)** | The signature added to emails sent from this address, as HTML | | **Signature Content (Rich Text)** | The same signature in a text editor. A change in either box changes the other | Select **Save** to save the address, or **Cancel** to go back to the list. To edit an address, double-click its row, or open the actions on its row and select **Edit**. To delete one, open the actions on its row and select **Delete**, then confirm. To delete several, tick them and select **Bulk Delete**. ### Attaching a tracking domain By default, the open and click tracking links in a sender domain's emails use a shared Clockwork CRM host. To use your own tracking domain instead: 1. Open the actions on a verified sender domain's row and select **Tracking Domain**. 2. Choose a verified tracking domain under **Tracking domain**, or **Use the shared platform domain** to go back to the shared host. 3. Select **Save**. **Tracking Domain** is not offered for a domain that is not verified, or for the system default domain. ### Deleting a sender domain Open the actions on the domain's row and select **Delete**, then confirm. To delete several, tick them and select **Bulk Delete**. ## Tracking domains A tracking domain is a host of your own, such as metrics.yourdomain.com, used for email open and click tracking and for website analytics, so tracked links and beacons carry your brand. **Administrator Tools → Tracking Domains** lists them. Each tracking domain is listed with its **Host**, its **Status**, **Verified** or **Not verified**, when it was last checked, and the **CNAME target** its DNS record must point to. **Search tracking domains...** filters the list. ### Adding a tracking domain 1. Select **Add Tracking Domain**. 2. Enter the **Tracking domain host**, such as metrics.yourdomain.com. Enter the host only, without "http://", a path or spaces. 3. Select **Add**. 4. At your DNS provider, add a CNAME record for the host that points to the **CNAME target** shown in the list. The copy button copies it. 5. Open the actions on the tracking domain's row and select **Verify**. When the host points to the CNAME target, its status changes to **Verified**. If the host points somewhere else, it becomes **Not verified**. If the record cannot be found yet, the status stays as it was, and you can verify again later. A verified tracking domain can be attached to sender domains and to analytics sites. ### Deleting a tracking domain Open the actions on the tracking domain's row and select **Delete**, then confirm. The tracking domain is removed from any sender domains and analytics sites it was attached to, and they go back to the shared host. ## Related - [Bulk email shots](https://help.clockworkcrm.com/marketing/bulk-email), sent from your sender domains - [Website analytics](https://help.clockworkcrm.com/marketing/website-analytics)
