In a SharePoint Designer 2010 workflow HTML email I was frustrated because I was unable to add images and tables directly from the editor. I thought rich HTML is not supported with this version but I found a quick way to add rich HTML in an email body message.
Use the following procedure to add images in a SPD email body in 2010
- First create your HTML in Dreamweaver or Visual studio 2010 or any other HTML editing tool
 - Then open your workflow in SPD 2010
 - Add a “Send email” workflow action from the ribbon
 - Keep the “Send Email” action selected/highlighted
 - Then navigate to the ribbon and select the advanced properties
![SPD Email body in 2010]()
 
 - Click advanced properties Select last option Body
![SPD Email body1]()
 
 - Click on the button (...) to open the text pad
 - Paste your HTML including head, body and HTML.
![SPD Email body3]()
 
 - Click "OK" and open the action from the workflow step.
 - Done!
 
Note
If you edit the subject or To/CC/BCC then don’t edit the workflow; go to “advanced properties“.
Choose for example the third option, the subject line can be edited if we use an edit workflow then automatically disturb the HTML and <imp> tag to be converted into text.
