Nacho Mail is the best commercial grade email+calendar app on Android today. It's secure. It's fast. Your email never ends up on a server in the sky, rather Nacho Mail is a true Exchange ActiveSync and IMAP native client. It's AI enabled, so Nacho Mail learns from your actions and will begin automatically putting hot messages in your Hot List for immediate action. You can train the app by marking messages as "Hot" or "Not", helping ensure that your email app is tuned to your needs. Never miss an important message again! Works with Exchange ActiveSync, Gmail, Google Apps For Business, Amazon WorkMail and all IMAP email services. Nacho Mail includes Enterprise Support for ACE (App Configuration for Enterprise), allowing Nacho Mail to be deployed through your enterprise MDM vendor.
Nacho Mail provides integrated calendar, contacts and email for users in a simple interface that was built for teams (sales teams, marketing teams and other groups) allowing for rapid triage, response of messages, and the ability to ensure that you always see messages from your VIPs in your Hot list. This is how enterprise mobile email is supposed to work, fast, productive and easy.
