    Please note: It’s important to keep these records active until you have completed all the steps below. Once you’ve successfully completed the move to your new email host, these can be deleted by ticking the check boxes and selecting Delete.
  8. Take note of the number next to the MX record in the Data column. This is known as the priority, and you will need to add the new record at a higher priority. We’ll explain this further in the next step.

  9. Add the new DNS records by selecting from the DNS Record Type drop-down menu.

    MX Record
    - Leave the Mail domain field blank. (If your provider mentions entering ‘@’ also leave the field blank, the record will still create correctly).
    - Under Preference, select the number (priority) required or use Custom to enter it manually. The number used for your new MX record must be lower than the number on your existing record. For example, if the existing is 10, you can use 5 or 0.
    - Enter the record for the new provider in the Mail exchanger field.
    - In most cases the TTL can be left as default. If your provider recommends changing it, select Custom and enter the number required.
    - Click Finish to save.
