Before you send your message you can make sure to preview it to ensure it looks like you hoped.
To preview a message you:
At the bottom of where you write your message, you'll see the option "preview your message". By clicking preview a message you'll see how it will look once it's sent.
2. Once you "click preview message" you have the option to both see how the message looks when sent as an email / SMS as well as the Portal.
If you would like to send a message to yourself you can press "send test email".
Please note that the link in the test email will not lead to the portal since it's just a test email.
