How to un-spam personal email address?

I don't know if it's the address itself or just Yahoo, but somehow my personal email address is showing up in some people's spam boxes. In this particular case, I'd been trying to communicate with an Amazon seller about a return and refund and was frustrated that he wasn't replying to any of my emails. Turns out my mails were going into his spam folder. That wouldn't concern me much as it can depend on each user's and network's spam settings, but this isn't the first time people have said messages from my Yahoo email have been flagged as spam.

So my question is, is there some way to check and see if my address is on some national spam list? Is there anything I can do to try and remedy this? I'm definintely not spamming anyone; I just want to be able to communicate with folks when I need to!
