A great OS X/iOS mail client with a lot of flexibility

In case you find Apple’s Mail.app somewhat limited, Airmail might be just for you. It is a very configurable client with a super-sleek UI, a true power-user app with a Mac-y look. The highlights: Quick reply (reply directly from the email you are reading), a minimalist window displaying the message list only (not the message contents), menu status icon, etc. Personally, at some point, I had a strange behavour when dealing with my iCloud account (it would just not send mails from my outbox), but the support was very patient and friendly dealing with my not always up to the point questions + very informative and knowledgable (thanks Steve, you’re the champ!). I can definitively recommend this app! To me it is worth every penny.

P.S. The iOS app is also quite good and I happen to use it as a default email client too.
