   We think it's too damn expensive to send email these days. We built Anypost on modern (non-cloudy) infrastructure to ensure we can offer a top-shelf product without having to hit you with the cloud tax. We're not looking to be the next unicorn. We just want a sustainable product that helps solopreneurs and high-volume senders get their message out without having to worry about the bill. We're around - feel free to ask questions!
