Have you sent email or is it proper to do so? Or do you think they'd be interested if i do it? I'm planning to sell a couple of domains to a very popular and big company.
The only thing I would comment or caution on is the potential for any ™ issues, absent any further information, IMHO.
Having properly addressed and researched that aspect beforehand, I would think that marketing to potential End user's (including companies and Corporations) would be wise ... as part of your overall domain reselling strategy. Can you be more specific as to the domain names and/or the company here?
There are also some very current threads on this general concept (End user's) in the "Domain Discussions" Forum at the present time, as well.
Thanks and Good Luck.
