We want the FROM address set to our domain so that 'via Shipstation.com' does not appear on gmail. We also want to include your spf/senderId records in our spf/senderId records, have the email signed with our DKIM key and have the links use our subdomain instead of email.shipstation.com.
Here's how this works on a few of the major ESPs:
