Hello, Recently our companies click urls started to appear on some "spam-lists" however the things we mail are not spam. Generally they are welcome letters and the like. We know how we can get around using the domain name in the anchor tag, but what about images? if we have say, <img src="http://our-blacklisted-domain.com/images/header.gif"> will we still get blocked? Thanks for any help you can provide!
Many images get blocked by spam filters regardless of the file location. Perhaps try hosting the image files on another domain.
