Once you've sent a campaign, you can view a report on it by going to the top menu Marketing tab, clicking Campaigns in the left menu then clicking on the campaign name.
What the numbers mean
Opened - The number of people that opened the email
Opens - The total number of times that an email has been opened.
Clicked - The number of people that clicked on the email
Clicks - The total number of clicks
Undelivered - The number of emails that have been sent but not confirmed as delivered to the recipient. Immediately after sending a campaign this will be all recipients and will reduce overtime as we receive delivery confirmation from each recipients mail server. It is normal that not all emails can be delivered which could be for any number of reason (eg. bounces, invalid email, marked as spam etc.). Read more about undelivered emails here.
Unsubscribed - The number of people that unsubscribed from the email
Open rate - The percentage of people who have opened the email
Click rate - The percentage of people who have clicked at least once on a link in the email
The 24 hour performance graph shows how many clicks and opens there were over the 24 hours straight after the email was sent.
