In our example, we'll use Cloudflare as our DNS manager, which we strongly recommend.&#x20;

{% hint style="info" %}
**Cloudflare rocks**

Cloudflare acts as your DNS nameserver, reverse web proxy, web application firewall, SSL provider, incoming MX record mail processor, and much more
{% endhint %}

Create a new TXT record for your domain or subdomain

When you send yourself a test message to Gmail, you can verify DKIM is working by clicking the three dots then **show original**
