Circular icon next to inbox emails

I have, what I think are, greyed-out circular icons with parallel diagonal lines in them next to each of my inbox emails listed. These are new to me. I think emClient upgraded and that’s why I have them. But what are they? Do I need them?

@Indiana It could be the eg: Contact (Avatar icon) associated to that email address.

If you have V8 EM Client, Click on “Contacts” at the bottom left and then click on “People” at the top left. Then dblclick a contact to open / edit it.

Now on the right side of the contact you will see the “Avatar / Icon” of that contact which by default is usually just a round greyish icon. You can “Right Click” on the picture to “Change the Picture” or “Remove the Picture”…
