Because of the way the contact DPO modal window is laid out, the text reads 'Reply to Message', which is very confusing for a user who has just clicked the link 'Contact Data Protection Officer'.

I'm wondering why the user's email address is shown at the top, and whether it could be removed?

Other possibilities would be to add some space between the email address and the text box and move the labels 'Reply to' and 'Message' closer to the email address and text box.
