# Things to Know About Journey Builder Triggered Send

When you create a Journey Builder email, a triggered send is created automatically. Activating the journey creates the triggered send definition that the journey’s email activity uses.

When you create a journey version, the previous triggered send continues to run. Activating a new version defines a new triggered send. Also, you can stop the triggered send that is associated with a Journey Builder email activity. You can modify the email’s content, then restart the triggered send to re-enable sending within the journey. The triggered send name is a system-generated value and can’t be modified. If an external key isn’t provided at the time of creation, the system adds a key.
