I received an email via my website from a customer who left out one letter from their name on their email address. When I responded to them it automatically bounced back. So I went to my website control panel and found an IP number from the sender. I didn't know what an IP number was so I Googled it and discovered I was able to input the IP number and find out where the email had originated from. Des Moines, Iowa. Then I Googled the person's name and Google corrected it for me, so then I Googled their name and Des Moines, Iowa and found there was one person with that name living there. I resent the email and the customer responded by buying the artwork through my Etsy shop. When I asked her how she found my website she said she had been in Seattle last April and saw my work at a coffee shop and kept my card. How very cool is that?
