Please do not send her that email. The tone- which has repeated apologies in it - makes it sound like you don't know what you are doing. Even if you don't, you certainly don't want a customer to think so. If you want to explain your pricing that's one thing, but keep it simple. And for heaven's sake, DO NOT offer this woman a discount.
I would send something along these lines:
Hi Jennifer, thanks so much for your feedback. It made me realize that I could add a an explanation of my pricing structure on my Facebook business page. For large decorated cookies with three colors on each cookie and a variety of colors in the order, my price is $1.00 per inch, and the crayon cookies were 4½ to 5 inches.
I looked at the Etsy shop you mentioned, and her cookies are beautiful! I found her Hello Kitty cookies comparable to the crayon cookies since they are highly decorated with three colors, and her price per cookie with bag and bow before shipping costs is $2.91 per cookie. When you add the shipping cost, they end up being $3.91 per cookie, which is more than $1.00 per inch since they are 3-inch cookies. Her mini cookies are much less because of the size.
There is also a possibility her rates are discounted because of the freshness factor. If you wanted cookies for an event on Monday, for example, she would have to bake and decorate the cookies the Monday or Tuesday before, let the royal icing on them dry for a minimum of 12 hours, possibly even 24 hours, before being bagged and shipped, and then you would receive them on Friday or Saturday where they would have to wait another few days until your event on Monday, and by then they're already a week old.
Hope this explanation is helpful. I know everyone has their own budget to work with. I completely understand if you decided to purchase from her instead, but hopefully I will have the opportunity to bake something for you again in the future.
Thanks Jenn!
