Thanks for asking about your email campaign! I first want to compliment you on the great use of colors to match the branding of your logo. I would suggest slightly reducing the size of your logo image though just so that it's not quite so close to the border. Remember, whitespace is good!
I also noticed a few different fonts are being used within the body of your email campaign. Try using the same font for consistency, and use emphasis (bold, italic, etc.) for headlines. A good rule of thumb for email design is less is more. The longer someone has to scroll the quicker you'll lose his/her interest in reading your entire email. You might consider not quite as much text as there's a lot to read. Nonetheless, it's great information and I like how you broke it up with images. I also like that you linked your logo image, email address and included some other important quick links.
And that's great that you included a coupon to entice your customers! Be sure to include a call-to-action for the coupon -- meaning how you want your customers to redeem it.
Awesome job, Arlene!
