Download HTML Mail Editor from the iTunes App Store.
The HTML Mail Editor allows you to easily write HTML emails by entering directly its HTML source.
It provides a split screen editor view showing the HTML preview as you type.
The most common HTML tags can be picked from a picker.
Note: HTML Mail Editor does not replace Apple Mail. It does not send the emails. The HTML Mail is placed in your Apple Mail's outbox and send via Apple Mail.
