I've been actively searching for an email client that gave me a universal inbox for all my accounts. As a consultant, I regularly have 3+ client email addresses in addition to my main 3-- work, personal, business campaign funnel. I love the sleek design and ability to reach inbox zero. I already have a good email system, so those who dont actively use folders may not be as wowed as I was -- and still am. Looking forward to continued updates, bug fixes and app integrations.
