Overloop AI

To keep your cold emails landing in inboxes, your sending domain needs a few DNS records set up. SPF, DKIM, and DMARC verify that your emails are legitimate, while a tracking CNAME enables link and open tracking in Overloop. This guide show how to add each record them correctly.

Google: DNS provider + <a href="https://admin.google.com/u/6/ac/apps/gmail/authenticateemail" rel="nofollow noopener noreferrer" target="_blank">Google Admin Console</a>

For Microsoft 365, DKIM is enabled by adding two CNAME records to your domain’s DNS. These records are generated by Microsoft for your specific domain.

Go to <a href="https://security.microsoft.com/authentication?viewid=DKIM" rel="nofollow noopener noreferrer" target="_blank">Microsoft 365 Defender</a> &gt; Email authentication settings (DKIM)

You’ll see your domain listed with a toggle on the right.

- If DKIM is already enabled, the toggle will be ON.
- If it’s disabled, toggle it ON and Microsoft will show you the DNS records you need to add.

In your DNS provider, add the two CNAME records provided by Microsoft. See the table above.

Wait for DNS propagation (this can take a few minutes up to a few hours).

Go back to the Microsoft DKIM page and toggle DKIM ON again if needed.

1. Go to <a href="https://security.microsoft.com/authentication?viewid=DKIM" rel="nofollow noopener noreferrer" target="_blank">Microsoft 365 Defender</a> &gt; Email authentication settings (DKIM)
2. You’ll see your domain listed with a toggle on the right.

4. Wait for DNS propagation (this can take a few minutes up to a few hours).
5. Go back to the Microsoft DKIM page and toggle DKIM ON again if needed.

Once the toggle is ON, DKIM is active for your domain.

Note: The hostname 'track' is chosen arbitrarily. You are free to configure another one within Overloop
