Marketing Campaign details

How do I find out more details about a specific marketing campaign? We have one called "Lead Box RN"....I believe this is the campaign for our "Sign up and Save today" sign up box....but is marked inactive and then is tagging sign ups as "Sept email group A" which I have no idea what this tag is. Basically trying to figure out which one of our marketing campaigns is for our coupon sign up box as i do not believe it is actually sending leads the welcome email with coupon when they fill out the box...

To view the name of marketing campaign for each sign-up box, you can go to the 'Contacts' then 'Sign-Up Boxes'

Please click on the 'Edit' button for campaign that you would like to edit

Now if you scroll down to see the 'Settings' box, you can see the name of the campaign here.

Ok great. So i think our "Lead Box RN" is our coupon sign up box...how do I now turn on the campaign to send the welcome email coupon when a lead signs up in this box. It does not appear to have been working since May where is automatically emails the coupon...

Here is a video that explains how to use campaigns:
