My company sends our single emails out in Journey Builder so that we can leverage Einstein STO, Path Optimizer A&B tests, and other segmentation splits. These "journeys" are always running, even after the send. This journey will never be used again. Should I be manually stopping these journeys after everyone in my Data Extension has received the email? It's a little confusing to see a journey running from months ago, and there is always a little fear that these Data Extensions might get updated somehow and these old emails would be sent out to new DE records. Is there a better way to do this than manually stopping the journey each time?
