You can benchmark against your past performance or compare to peer organizations.
Each organization has its own strategies, goals, and execution tactics but you all are striving to reach and engage with a similar consumer target audience. When you monitor and measure the effectiveness of campaigns run by other brands the data you gather can help drive your decision making without the expense and risk of trying them all yourself. This does not mean you should simply be a copycat brand, but understanding the competition will help you make informed decisions about your own strategy going forward and measure your own success with market context.

They are also offering a free trial of their product which was expensive for nonprofits last time I checked.
