Changed email profile as a company change over occured reference old email still

We have changed companies so with that happening our emails have changed. I changed our email setting profile and did an email test which worked. the problem were having now is the notification pipelines are not working. even with the updated profile that can send emails i am getting this error looking at the logs when i do a pipeline test is trying to send as the old email and getting an deny because that email is no longer available. is this a cache situation with the pipelines holding the old email?
