The best thing about Power AddOn is that it helps me to manage all my marketing campaigns in one place, so I don't have to track each individual email individually. It's not very user-friendly, it takes some time to get used to it. I wish you could add more templates and also make it easier to customize emails. Also, sometimes it doesn't send out emails, but instead shows an error. So far, I haven't found anything that I dislike. I would definitely recommend this product if you are looking for a way to manage your marketing campaigns. You can use PowerAddon to create different types of emails such as landing pages, blog posts, event notifications, newsletter subscriptions, etc.
