The post to email function and the reply from email feature.

Intuitive UI, mimics other social media feeds so easy to use. I like the option to announce my post via email as well

I love the ability for members to interact with the platform completely from their inbox so they don't have to check a separate platform if they don't want to. The ability to send SMS or email campaigns from Mobilize is incredibly helpful so I don't have to consistently cross-check distribution lists with other platforms. Similarly, being able to send event invites and manage RSVPs on the platform is helpful. The ease with which members can connect with each other (and filter the member database by job scopes, areas of expertise, or anything else that's public on members' profiles) is great. Our users were hesitant to transition to a new platform, but after some initial pushback, we haven't received any complaints about the platform's features or usability.
