In order to utilize the email automation functionality of Campaigns, you will want to link your different campaigns together. To add subscribers to more than one campaign, you can use the "Trigger" options available in Campaigns. These can be used to link more than one campaign together as well. This article explains how you can link multiple campaigns together using the different triggers available in Campaigns.
Linking campaigns using "On Subscribe" trigger
With Campaigns, subscribers can begin receiving your campaign based on the "On Subscribe" trigger you select. You can have multiple campaigns created using a combination of different "On Subscribe" triggers. To create the "On Subscribe" trigger for your campaign, first select "On Subscribe" as your trigger.
Next, from the first drop down menu select the option for your "On Subscribe" trigger.
Then, you can select the different adding method for your "On Subscribe" trigger. This could be one of the five adding methods to a list, the ad tracking value of your sign up form, or a specific country based on the subscriber's IP address.
For example, if you created two campaigns and each campaign contains a different "On Subscribe" trigger, subscribers could be added to multiple campaigns if they meet both "On Subscribe" criteria.
Linking Campaigns Using "Tags"
When creating your campaign, you have the option to add a tag(s) to subscriber's information. This can be accomplished by using the "Apply Tag" action from your left hand sidebar.
From the right hand sidebar of the editor, enter the tag(s) that you would like applied to subscriber's information or removed from their information. For our example, the tag "completed-prospect-campaign" is added to the subscriber's information.
Then, once you create another campaign, select the "Trigger" for "Tag Applied" and enter the desired tag from your previous campaign.
