Among the several types of triggers available when designing your own automation workflows, the "When someone unsubscribes from a specific list" trigger is the type of trigger which reacts when someone unsubscribes from a specific mailing list, by setting your automation in motion.
A. Setting trigger parameters
The only parameter that you need to define on this type of trigger is choose from which list someone needs to unsubscribe in order to trigger your automation.
After you're done, click on the Save button to have your trigger ready and waiting inside your workflow.
B. Using the trigger
It's important to understand that no actions can be performed on members who have unsubscribed from a mailing list. Why 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 Moosend account are set to: "Unsubscribe users from this mailing list, but send to them from other mailing lists".
You will need to create two separate automations, each one with its own trigger and actions:
- Automation #1: When someone unsubscribes from list A, subscribe them to list B.
- Automation #2: When someone is subscribed to list B (because of Automation #1), send them an email campaign, then unsubscribe them from list B.
Using the above idea you can design your own automations to perform actions on whoever unsubscribes, such as contacting them to say you're sorry to see them go, or any other type of action from the ones available. Just make sure that you remove them from your second list afterwards, since they did request to be unsubscribed!
