Suggestions

• I think all the emails that already was added, should be shown always with the background and the close button instead of only when the mouse is hovered, because that way permit the user understand that is in a different state than the one that is being filled, also permit the user have a general view of how remove them

• When there is an error in the label, should be a close button.
