(From youngkim977@gmail.com ) Hi there!

I'm a freelance online marketer looking for potential clients. I sent you this email because I noticed that your website is missing essential elements that would allow it to rank higher in Google and the other search engines. I can fix (for a cheap cost) the problems on your site that are not allowing it to rank well. 

Kindly write back to let me know if you're interested and I'll give you a free consultation to show you how this will be done. The info about your website's potential and the steps you can take to make it rank higher will be useful for your business whether or not you take advantage of my services. I hope to speak with you soon!
