23.94.151.60 attack
(From heathere011@gmail.com) Hi there! 

Have you considered making some upgrades on your website? Allow me to assist you. I'm a freelance web designer/developer that's dedicated to helping businesses grow, and I do this by making sure that your website is the best that it can be in terms of aesthetics, functionality and reliability in handling your business online. Are there any particular features that you've thought of adding? How about giving your site a more modern user-interface that's more suitable for your business? 

I'd like to talk to you about it on a time that's best for you. I can give you plenty of information and examples of what I've done for other clients and what the results have been. Kindly let me know if you're interested, and I'll get in touch with you at a time you prefer. I'm hoping we can talk soon! 

Thank you,
Heather Ellison
