When I send HTML e-mails from my website with my logo as an embedded image, Hotmail hides it by default with the message Attachments, pictures and links in this message have been blocked for your safety.

Since this is my logo, it makes the e-mail look very funny. Is there some certification/verification process to allow embedded images from my domain to be shown by default in Hotmail and other major e-mail service providers?

Basically, no there is no certification program. All major web email clients do this and there is no way around it.

Gmail always displays attached (ie. embedded) images - but as an attachment, after the message. External images are blocked by default. In fact, so does Hotmail. – w3dk May 17 '12 at 15:01
@w3d yes, while thats true it doesn't answer the question asked or help patrick. – toomanyairmiles May 17 '12 at 16:32

You could put the logo on your website and use the <img> tag to display the image in your email. Email clients like Outlook and Gmail ask the user if they want to display the images.

I tried that, but users are still prompted to choose whether they would like to display the image or not. Since it's just my logo, I don't want to inconvenience users by making them click to display it; if I can't display it automatically, I'll just use text instead. – Patrick Kenny May 17 '12 at 15:27
He's running into the security blocks in gmail and hotmail that prevent images loading unless the user ascents to their display - there is no way around it, it doesn't matter where you serve the content from. – toomanyairmiles May 17 '12 at 16:31
