Technology / Email / Open Rate: The number of HTML message recipients who opened your email, usually as a percentage of the total number of emails sent. The open rate is considered a key metric for judging an email campaign's success, but it has several problems. The rate indicates only the number of emails opened from the total amount sent, not just those that were actually delivered. Opens also can't be calculated on text emails. Also, some email clients also users to scan message content without actually opening the message, which is falsely calculated as an open. See preview pane.
