I would like to send an email and this email should contain a column that gives me a "dropdown list" so that the receiver of the email can choose from the options and reply back.
How can this be achieved by using blue prism?
You've got one major issue here. Do you know that the receiver of the email will have an email client that is configured to interpret/display HTML? If so, you can use the MS Outlook VBO to create and send an email using HTML. Then it's just a matter of you figuring out the proper HTML to display the list.
