Setting Up a Dedicated Sending Domain

Overview

Establishing a whitelabeled sending domain requires adding additional CNAME records to your DNS settings with your hosting provider. We provide the records below, which you copy/paste into your DNS provider.

If you plan to use a whitelabeled sending domain, Klaviyo requires that you warm this sending domain by following the instructions in this guide.

Add the following 3 CNAME records to set up your dedicated sending domain:

Type Hostname Value
CNAME send u161779.wl030.sendgrid.net
CNAME s1._domainkey s1.domainkey.u161779.wl030.sendgrid.net
CNAME s2._domainkey s2.domainkey.u161779.wl030.sendgrid.net

Depending on your DNS provider, the name of the Hostname and Value fields in the example above may differ. The next section covers a few examples of adding these CNAME records to popular DNS providers. If you're still having trouble, check out our links to the documentation for some popular DNS providers for more information.

After you've updated your DNS records, you must still email Klaviyo support in order for us to validate and activate your records. Please email us if you are updating your records.

Examples of Adding CNAME Records

Below are some examples of updating CNAME records on a few popular DNS providers.

GoDaddy

You may have other records as well.

Google Domains

Below is an example of what the Klaviyo CNAME records look like when added to a domain managed by Google Domains.

You may have other records as well.

Digital Ocean

Below is an example of what the Klaviyo CNAME records look like when added to a domain managed by Google Domains. This domain is genobeanos.com. Notice how Digital Ocean automatically appends this name to the hostnames that were added.

You may have other records in addition to these.

Cloudflare

Below is an example of what Klaviyo CNAME records look like when added to a domain managed by Cloudflare.

You may have other records in addition to these.

When adding the CNAME records make sure you bypass Cloudflare's traffic filter. If you do not you will get the following error:

DNS Validation Error (Code: 1004): Invalid proxied mode. Record cannot be proxied (Code: 9041)

To bypass the filter click the orange cloud icon so it turns grey during the setup process.

Tips for Where to Update your DNS Records

You can update your DNS records wherever you registered or manage your domain names.

Not all domain registration services will allow you to edit all DNS records. If you cannot update the records below, contact your DNS provider for information on how to get these records updated.

The process of editing your DNS records will depend on what domain provider you are using. We've compiled links to documentation for some common providers here:
