The ability to target my list effectively for marketing campaigns, with very little effort from me! I had no idea how much work was required in order to create lists or get them created - Reach Dynamics has made this process quick & easy for us by providing a turnkey solution that can be used by any size business.
As mentioned above, targeting is also great- reaching our customers at their place of business when they are most likely to interact w/us (in store) versus online where we may not reach as many people.
