Hello @ThatMatt ,
Your campaign looks amazing! The concise length of the campaign, linkage to your website, and usage of just a few colors make this email ideal for engaging your readers. One critique I would make, is to not be afraid to be a little more descriptive at the beginning of your emails. Adding a little background to your cause will give a more inviting and encouraging feel to your emails. With that said, I would also recommend considering using a personalized greeting. These greetings can be a great way to add a personal touch, letting the customer know you are aware of who they are. Here is a link to our FAQ that talks about adding a custom greeting. Otherwise, as said earlier, your email campaign is on the right track with best practices.
