With a Mac computer it’s easy. Simple browse to the web page you want to send, go to FILE>SHARE>Email This Page.
Then when the email window opens up, look to the top right corner drop down box and make sure that “Send Content As Web Page” is selected.
Alternatively, you may already have published your latest post on your website. Why not just try selecting, copying and pasting into an email straight off the website. More often than not, it’ll just copy all the style layout as well (though not always – can but try though!)
