In the member list, click or tap anywhere in a member’s row—except the checkbox—to open a page that contains their membership details.

(Clicking or tapping the checkbox in a member’s row on the Members page selects the row so you can perform an action using the Actions button at the bottom of the Members page.) 

Note: When you are reviewing a member’s email delivery history, be aware that the Groups.io system stores only the 20 most recent successful and attempted email delivery results.
