A DMP stands for a couple of different things:
- Data Management Platform (software that, usually marketing companies, use to collect, store analyze, and use data from individuals/users).
- Debt Management Plan (an agreement between two parties: A debtor and any creditors, that helps the debtor pay off the money owed in a structured way that everyone agrees to)
There are many more things that DMP could stand for, here's a longer list I found: www.abbreviations.com/DMP
