Hello @user704188 ,
Dynamic content is a great way to customize the messaging your contacts receive, without having to do tons of future work. It can be used for ads/coupons, language differences, content based on previous interactions, and more. It's also a good way to keep your email lists and email sorting cleaner.
With that said, if you could describe your needs in detail, we'd be happy to provide some insight regarding your specifics. And hopefully other Community users will be willing to chime in with their experience using the tools, and what elements have and haven't worked for them.
In dynamic content is there is only 2 selections is or is empty. I need something like contains. We have a custom field that puts data like GEN,HOME. Any ideas?
