I understand what Mailpile is. It&#x27;s a self-hosted email web client.<p>What is Nylas? The website doesn&#x27;t seem to be written for me, but for PHBs. Apparently you have great business, design, and APIs, but what is it that those things do? Are you an email client? A server? A webmail service?<p>What makes you different from Gmail or from Mailpile?
