How does the "When someone unsubscribes from a specific list" trigger work

Among the several types of triggers available when you design your own automation workflow, the "When someone unsubscribes from a specific list" trigger is the one you need to choose when you want to set an automation in motion as soon as someone unsubscribes from a specific email list.

A. Setting trigger parameters
The only parameter that you need to define on this type of trigger is to choose from which list someone needs to unsubscribe in order to trigger your automation.when_someone_unsubscribes_from_specific_list_trigger_1.png

After you are done, click on the Save button to have your trigger ready and waiting inside your workflow.

B. Using the trigger
It is important to understand that no actions can be performed on members who have unsubscribed from an email list. So, why should you have such a trigger if you can't perform actions on unsubscribed members? The answer is simple: you can subscribe them to other lists, where you can take advantage of all the available actions. First make sure that the unsubscribe settings on your account are set to: "When unsubscribing users from a list, send to them from other mailing lists".
Then you will need to create two separate automations, each one with its own trigger and actions:

Automation #1: When someone unsubscribes from list 'mailing list 2', subscribe them to list 'mailing list 1'when_someone_unsubscribes_from_specific_list_trigger_2.png


Automation #2: When someone is subscribed to list 'mailing list 1' (because of Automation #1), send them an email campaign, then unsubscribe them from mailing list 1.when_someone_unsubscribes_from_specific_list_trigger_3.png


By using the above option, you can design your own automation workflow to perform actions on whoever chooses to unsubscribe. It will be easy to contact the people who unsubscribed to say you are sorry they opted for this, or to perform any other type of action from the ones available. Just make sure that you remove them from your second list afterward, since they requested to be unsubscribed after all.
