It's been useful in helping out with marketing as well as having other means of reaching clients such an email addresses plus we can keep up to date using their system if our offices are closed due to covid19! There isn't much but it works at this moment in time when I am unable to attend office meetings then online would be ideal (but not essential) Easy to use and the customer service is great. The support is always there when you need it. I can't think of anything I dislike. The service is great and they are always here to help. I have hosted two events for my company and both were very successful. The first event had over 1,000 people. The second event had over 4,000 people. With the help of Arena, I was able to get these events to happen and everyone came out for my company's events.
