Greetings,
After completing the website and created required emails and updating SPF records, 
email delivery is fine and doesnot go to spam,
now the only thing is that the mail tumbnail doesnot contai the image of sender though I have created gravatar profile,
Am I missing some thing, 
Need help, so that the email should have senders image in thumbnail as we see in gmail or any other mail services.
