Good work with your email, overall. You do a good job introducing your group and your purpose. Including your main topic in the intro is also beneficial in engaging your reader. Setting your topic at the beginning only strengthens your later paragraphs. The background information in the body paragraphs reinforces the persuasive elements of your email. Paragraphs are engaging in style, as are sentences. You do need to proofread it one more time. You're missing a couple commas, and the first paragraph is a little wordy. Make sure you have website correct throughout.

Email if you have questions. Thanks,

Kevin
