With many marketing technologies available, marketers need to stay ahead of the curve and take advantage of these solutions while they can. Marketers should know what technologies are best suited to their business or clients. A standard data-driven marketing stack is made up of 3 foundational building-blocks:

1. Campaign management. This technology relates to the creation of campaign groups targeting specific user types and monitoring how effective different campaigns are at a given moment in time. One of the most common forms of marketing is through email campaigns and there are lots of technologies that can help., such as MailChimp or Aweber.

2. Analytics and reporting. Analytics tools provide granular information about the groups targeted by different marketing campaigns, such as how users behave and how they engage with a specific campaign (likes, shares, sales, etc). This information is useful for the marketers because they can optimize the customer experience to meet customer expectations in the future. Robust analytics reporting provides a clear output of the data to enable marketers to make informed decisions. But it also helps with data visualization techniques which can be distributed among internal stakeholders via such as graphs, tables and pie charts. 

3. Optimization. Once marketers have access to the right information, they can refine different marketing strategies and make improvements over time. When a business understands the contributions to marketing activities, they can begin to deploy their money more effectively.
