You will need to login to your iwantmyname account, and then in your dashboard click on the domain name for which you would like to add the MX records. On the next page, click on manage DNS records to go to the DNS dashboard.
2. Choose MX from the Type drop-down menu. This will cause the Priority field to appear. Enter the priority / preference number. Note that 0 (zero) cannot be used. If your email hosting provider has instructed you to use 0, use 1 instead.
3. Enter the MX record DNS value, e.g. ASPMX.L.GOOGLE.COM or mx2.zoho.com in the Value field. You will likely have instructions to add multiple MX records, and each one will have to be slightly different.
4. You can leave the TTL field as is.
5. Click the blue add button to add the MX record to the domain's zone. It will appear in the list of DNS records for your domain.
6. Click the green Save DNS Settings button to save the new settings.
Note: many email hosting providers give instructions to add quite a few DNS records to set up email. We have one-click installs for many of these providers, like G Suite, Zoho, or FastMail so you don't have to type everything in manually.
Check out our App Marketplace for the full selection of email hosting provider installs.
