The message you create for your web site will differ from the message you create for the boiler-plate at the bottom of your press release, which will differ from the message you create for a webinar—because each is responding to specific needs. But each would follow the And-But-Therefore template you have established.
This is an interesting perspective. While the way we convey our message, product, etc. changes depending on the use case, having a standardized template on how to convey it seems useful. Especially when considering that one message often needs to be translated into a number of forms, having a template for your message that you can simplify or further elaborate could be very useful.
