Notes

This is the latest version of an email which I send periodically, offering customers the opportunity to pre-pay for SaaS in return for a discount. The benefits to the SaaS company are better cash flow and reduced churn rate. The benefits to the customer are, well, in the email. This genre of email has produced hundreds of thousands of dollars in pre-pays for some companies I work with, and it rarely requires any more work than this example.

I've put $79 is as a placeholder for the cost of the user's plan. We calculate that for each account, naturally, along with the billing contact's name.

`UIStatusBarStyle` in iOS 7

The status bar in iOS 7 is transparent, the view behind it shows through.
The style of the status bar refers to the appearances of its content. In iOS 7, the status bar content is either dark (UIStatusBarStyleDefault) or light (UIStatusBarStyleLightContent). Both UIStatusBarStyleBlackTranslucent and UIStatusBarStyleBlackOpaque are deprecated in iOS 7.0. Use UIStatusBarStyleLightContent instead.

How to change `UIStatusBarStyle`

If below the status bar is a navigation bar, the status bar style will be adjusted to match the navigation bar style (UINavigationBar.barStyle):
