I have email ID's hosted with Zoho and I have integrated that with Gravatar thinking that my emails will look professional. Unfortunately recipients does not see my Gravatar images. 

When I checked with support, they said that Gmail does not support that feature but the fact is that gravatar is not working even when you send emails from Zoho to Zoho.

I am not sure why Zoho is launching features without really testing it properly. Anybody has a solution?

Thanks
