LabVIEW
Rich Text Email Message Control
There are several examples of using a Rich Text ActiveX control but I admit I've never used them in a real program yet.

I've sent emails using LabVIEW that have custom formatting but they are in HTML format. I'm not sure how easy it would be to allow the user to make a rich text message, then convert it to HTML and then send that.
So here is one example of what I've been doing latelly. We have a lab monitoring system that logs events into a SQLite database. Once a day a query is made to the database to see what events happened in the last 24 hours and sends out an email summary. At first I was going to send it as an image of a table that was an attachment in the email but then things had scaling issues, and wouldn't look nice on your phone if that is where you read the email. Also for a table it would be a relativly large email. So I looked into sending the email as HTML and it seems to work. Here is the body of an email I send as a string which creates a table. This string is created based on the database query.
<!DOCTYPE html>
<html>
<head>
<style>
table, th, td {
border: 1px solid black;
border-collapse: collapse;
}
th, td {
padding: 5px;
text-align: left;
}
</style>
</head>
<body>
<h2>Summary from<br>2017-01-04 08:50:19<br>to <br>2017-01-05 08:50:19</h2>

The hidden table above is what the HTML text creates. I then sent this string using a gmail account using the code posted here, or here. The result is a nice HTML table in an email that can be viewed and scales on other devices. My suggestion for you is to find a way to have a rich text editor, that the user can put text and formatting into, and then when they click Send, it actually saves that as an HTML in a temp file, and then you read that temp HTML file and send it.
