What does Cision do well? Cision offers marketing and communications professionals an easy to use, all-in-one place solution for their needs. In my agency, we use Cision's PRNewswire service for press release distribution as we see this product as the best one out there. We also love how responsive their customer service team is. They've been great for sourcing quotes and answering questions about distribution analytics/number of outlets that would potentially get a release.
What does Cision not do well? Nothing comes to mind.
What do you wish you had known about Cision before using? That they had so many other products/services. I think Cision could've done a better job advertising these service offerings, but now I'm aware of them.
Have you used a competitor to Cision? If so, how does it compare? No, I have not.
