Great question that I’m sure we are all feeling right now.  Our advice is that yes, you should be doing digital marketing, however make sure that what you are sending/posting/publishing is relevant to your audience right now.  In short:
Make sure you are addressing a need with your communications
Make it creative and engaging
Send it to the relevant people
Don’t pop up out of the blue in someone’s inbox unless it is going to make sense for their current situation.
