Open Source Marketing Automation
Marketing automation sits on the seam between your contact list and the inbox: it holds the behavioral data, fires the journeys, and quietly shapes whether your mail actually lands. That logic is too central to rent from a vendor who can change it under you. The open source options here let you own both the audience and the rules that move people through it, on a stack you can read and adjust.
