I have just spent hours and hours thinking I was deleting contacts who were suspended. It still looks like they are still there but have a line through their name! I am trying to weed out my contacts. Am I doing something wrong???
You are doing everything correct. When you look at the reporting for an email that you have deleted the bounces they will appear with that line. This is so you can always see who bounced but also who has been deleted. If you search on the contact page for those emails you will find them deleted.
