WP Mail From II Going to Spam – MSN

I am in the process of rebuilding my site on WordPress. I have created a dedicated email account on Go Daddy = ecard@susanmarksphotography.com – so I can use this email address with ecard Lite (this app recommended to use your plugin). When testing in WordPress, all emails sent to MSN.com mailboxes goes to spam. I have the “from name”, “from email address” set as ecard@susanmarksphotography.com in the WP Mail From II and both boxes are checked marked to override. Do you have any recommended troubleshooting for me to try? Thank you in advance.
