CloudMagic is an alternative email client for iPhone that may look like any other third party email app but don't be fooled. The main goal of Cloud Magic is to provide the best search tools an email client can offer. Not only can you search individual accounts, you can search all your accounts at once, an invaluable tool for those of us with lots of inboxes.
If you find yourself struggling to find emails from a specific person that you know you saved, search can be daunting, especially if you have a lot of email accounts to manage. CloudMagic supports pretty much any account type you could have including Gmail, Hotmail, Yahoo Mail, Outlook.com, iCloud, Google Apps, Microsoft Exchange, Office 365, Mail.com, GMX, AOL and other IMAP accounts.
CloudMagic is free to use for up to 3 email accounts. Upgrading to Pro gets you faster support (if you ever need it), an unlimited number of inboxes, an option to passcode lock the app itself, and the ability to remove the 'Sent from CloudMagic' footer. A Pro subscription will run you $50 a year which makes it a more expensive offering, but still not bad.
