Why Email Fields are Ordered in Reverse

Patrick Rhone shared his thoughts on email clients and his ideas to change email as we know it:

I want to write my email like I write my letters. I want to compose it first, then address it, and then come up with an appropriate subject. I’ve never understood why the question of subject comes before that of composition. In my opinion, it should come last.

I believe we need email clients that offer different layout designs for composing and reading. The current layout design and fields ordering are optimized for the recipients to read, not for the composer to write.

That's why I use Drafts to compose my email before I send them to Sparrow.
