One of my favorites in eCRM is eMail. You can drive sales, transaction, awareness and so much more for a high ROI. In the past, batch and blast has been very effective for many brands for a long time. In 2017, look at other opportunities to segment your lists and test how personalization and segmenting does for you compared to batch and blast. Test offers, messages, creative and so on with your segments. I would also take the time to look at all of your current programs (print them all out and put on a wall) and make quick adjustments that will benefit your customers.
