Send personalized email

Hi,   I am trying to send emails with personalized greetings, using the Email_Connector module, but not with pre-defined templates.   The user can select a list of contacts and provide the content in a WYSIWYG editor. I want them to be able to add a token e.g. '"Dear {%FirstName%}" into the message, but having a hard time to figure it out how could I do that.   What would be the easiest way to replace the {%FirstName%} in the email message (basically in a string)? Is there any function to simply replace this in a string? I am trying to figure out how the MxModelReflection replace token works, but no luck and cannot find any documentation on it either.    Thank you all in advance!
