Currently we run a "happy work anniversary" campaign in our Marketo instance to internal employees. Our parent company uses Exact Target right now and wanted to start using Email (O)pen because they specialize in internal communications. I wanted to see if Marketo could support what they're looking to accomplish so they wouldn't have to work with yet another email company. They have an internal HR server that Email (o)pen communicated to every 24 hours so it can dynamically update new or old employees. Does anyone have experience running internal campaigns and how do you handle the need to update employees daily without manually having to import or remove records? (We are a finance company with tight rules so we need to update employees daily).
