Different text for emails to paid and unpaid subscribers

It would be great if there was a function that enabled different text to be sent to paid and unpaid subscribers in newsletter emails.

It could be implemented in a similar way to the current functionality to have text which only appears in email vs in the post. There could be a “paid email” and “free email” sub-option.

This will enable tailored aspects of content without having to make completely new duplicate posts.

This would be very useful indeed - especially to make call to action to convert free subscribers to paying subscribers.
