Parts Portal's capacity targeting feature identifies which machines have open production time, then matches that availability to customers who have previously ordered parts that run on that equipment. Shops send a time-bound promotion only to that matched list, rather than emailing their full customer base, which makes the offer relevant and trackable. It is an understandable instinct. It is also a costly one. A generic promotion does not know which machines are actually idle. It often pulls in work for equipment that is already running at full tilt, while the machine that actually needs filling stays empty. ### **The Cost of Spray-and-Pray Marketing** Shops that rely on blanket promotional emails usually run into three problems at once. Overhead keeps accruing on the idle machine regardless of whether a promotion goes out. There is limited visibility into which machines have open windows and when. And because the offer was not targeted, it is nearly impossible to tell afterward whether the campaign actually worked. ### **How Targeted Capacity Promotions Work![Website (2)](https://custompartsportal.com/hs-fs/hubfs/Website%20(2).png?width=344&height=430&name=Website%20(2).png)** Parts Portal flips this process. Instead of emailing everyone, a shop can filter their part library by the specific machines that have open capacity, then send a promotion only to the customers whose parts run on that equipment. **Parts Portal matches open machine capacity to customers who already order parts that fit it.** Each email goes out with a time-bound discount code and a specific list of eligible parts. - Filter available parts by machine and customer in minutes - Attach a time-bound discount code to create real urgency - Send only to customers whose parts match the open capacity - Track quotes and resulting orders in one place   ### **The Time Saved** Shops using this approach report building and sending a targeted capacity promotion in minutes, compared to the days often spent manually cross-referencing customer history with open machine time. **See why this matters at the industry level.**  [US Manufacturing Capacity Utilization Is at 76.2%. What That Means for Your Shop](https://custompartsportal.com/blog/us-manufacturing-capacity-utilization) ### **FAQ** **How does Parts Portal help fill idle machine capacity?** Parts Portal identifies which machines on a shop floor have open production time and cross-references that availability against the shop's part library to find customers who order parts that run on that equipment. The shop then sends a targeted, time-bound promotion only to that matched group. **What is targeted capacity marketing for job shops?** Targeted capacity marketing means sending promotional offers only to customers whose work fits a specific machine that currently has open time, rather than emailing a shop's entire customer list. **How long does it take to build a capacity promotion in Parts Portal?** Shops typically report building and sending a targeted promotion in minutes, compared to the hours or days often spent manually cross-referencing customer order history with open machine time. ## Share this post [mailto:https%3A%2F%2Fcustompartsportal.com%2Fblog%2Fhow-targeted-promotions-fill-idle-machine-capacity](mailto:https%3A%2F%2Fcustompartsportal.com%2Fblog%2Fhow-targeted-promotions-fill-idle-machine-capacity) ## Keep reading ### [![](https://custompartsportal.com/hs-fs/hubfs/Blog%20cover%20picture%20template%20(1).jpg?width=1920&height=1080&name=Blog%20cover%20picture%20template%20(1).jpg) More Orders, Less Profit?
