I had been sending out press releases for years using Constant Contact and iContact but was introduced to Prezly by a business associate. I think it is a great option to manage all PR contacts on multiple lists, tag them by media type or client, set up newsrooms, add in photography and blast out. You can also track who is opening your releases and pitches.
Prezly is extremely easy to use and clear. I love being able to have all of our media contacts in one place and to keep them incredibly organised. Also, I appreciate that newsrooms are available so that our clients' latest and past releases can all be easily found and shared with the appropriate journalist, also through Prezly.
