Step 3. Adding DNS to Godaddy

On the GoDaddy Dashboard, go to Domains> Manage DNS> Add New Record, then add the "TXT" value" that you got from Central.

Step 4. Domain Verification

After adding the TXT Value on GoDaddy, go to Central and verify the Domain ownership.

Once it's verified, you’ll see a prompt, as seen below.

Now, go back to the GoDaddy dashboard, under Domains>Manage DNS> Add New Record, and add the MX Record.

Step 8. Publishing of MX Records

Note: Publishing will take a couple of Minutes.
