The Internet is a great resource. We still have to beware of scam artists preying on real artists who passionately want to sell their art.
Be Alert. Keep up with the common art scam emails. Don't be clueless, learn to recognize a scam. A good resource is Art News Blog. I myself have gotten these types of inquiries and now delete them without deliberation. One artist friend was nearly scammed this year after corresponding with a con artist over a period of a time. If you're not sure about an email inquiry, ask other artists or business colleagues who may be able to spot a fraud.
Words of wisdom...Be skeptical... If an offer sounds too good to be true, it probably is. Do your homework.
