A fun fact I ran into this week — some fellow email marketers may have already known this — Gmail doesn't allow for links to be black (color = "black" or #000000). They default back to the standard blue! They override even when using in-line CSS (meaning, I changed the link color manually or near the link in the HTML code).
The biggest step is realizing what was happening. (Surely Gmail thinks it's saving their inbox users from spammy "hidden" links in the text.) I figure the easiest solution is to just use a color that's almost black (but not "black" or #000000). For example, I used #000001 and it seemed to work just fine — and still looks black.
