It never fails that I receive a domain inquiry in regards to buying a domain name I own, or questioning whether the domain name is for sale and how much.
Most of the time, such domain inquiries are nothing more than tire kickers that have no intent to buy.
Such tire kickers inquire only to either curse me to the hills and back, try to threaten me with legal action with no leg to stand on, or they try to explain to me why I’m asking too much for the desired domain.
No matter their negative response, such inquirers end up right back where they started: not owning the domain!
Most of the unsuccessful buyers settle for a hand-registered domain that is nothing more than a cheap knockoff of the domain they really desire.
However, there are those few occasions where someone will lowball me for a domain and respond to my counter with a substantially higher amount than their initial offering.
I tend to sell 90% of those types of domain inquiries.
All in all, like everything else in life, you can’t judge a book by its cover when initially fielding domain inquiries.
