Horde is one of the many email programs offered through Suncoast Hosting and is the best to use for inserting URLs and jpegs as it has a built in HTML editor. When you are composing a message click 'Switch to HTML composition' which is right above the body of the email. Through this feature you can edit the fonts and colours, and insert links and images. Horde does all the HTML coding for you making the process very simple. SquirrelMail is a plain text program, so you would have to learn HTML and code it yourself.
Please note: As of November 2022, Horde is no longer supported by cPanel. Every cPanel server now runs Roundcube for Webmail.
