Hi,
It makes a difference if the user subscribes via the frontend or if you subscribe them via the backend (e.g. import users and subscribe them to a list).
When the users subscribes via the frontend everything will work as you expect. You can set a trigger "when the user subscribes" in your foow-up campaign. As sson as the user subscribes the follow-uyp gets triggered.
When you use backend features like importing users and subscribing them to your list the follow-up does not get triggered. This is a precaution to prevent you from accidently sending these follow-up mails, for exambple when you import a huge number of users..
To get the follow-up campaign triggerd for these users that you have added in the backend you can run a mass action or automation to trigger the follow-up campaign for these users.
You could do something like this:
- import 100 users and subscribe them to YOUR LIST and to a TEMP LIST
- Setup a Automation, trigger it daily and target the users on your TEMP LIST and set the action "Subscribe to a follow-up" and add a second action that will unsubscribe these users from your TEMP LIST.
If it's only a one time action you can use a mass action instead of a daily automation.
