How do you store and manage your messaging for other Marketing team to use?
It's important to create a single source of truth so that stakeholders know where to look for the latest and greatest. If your company has a wiki (Notion, etc.), create a messaging hub within your marketing space. If they don't have a wiki, a Google Drive or Dropbox folder will also work. The more tailored you can make it to different audiences, the better. Make it simple for them to find the messaging that they need—whether it's for GTM purposes or product.
PMM can sometimes feel like the "messaging police," but it's important to call out and update outdated messaging if and when it's seen. Pointing people back to the single source of truth will help build positive habits. It's easy for stakeholders to just use an old document or collateral that might contain outdated messaging and it's more work to go find the most recent update. With a little bit of friendly coaching, most stakeholders will abide.
We leverage internal tools to store and organize messaging frameworks (and all other marketing assets). Once messaging is fully documented and approved we upload it into tools like Google Drive or Seismic. Defaulting to open internally is important so your peers and partners can easily access.
In an ideal world you have a fairly uniform and consistent format you use across all your products/product areas for easy consumption.
It is also important to monitor regularly and ensure that there remains only a single source of truth. Sometimes as teams start leveraging documents, version control can become a problem.
Make sure you keep your source of truth up to date or usage/trust may falter.
