If you want to talk to people through email, SMS, Facebook Messenger, and others, you can do it through Courio.
A marketplace of plugins and lots of customization options allow you to do things your way, similar to Google Chrome's Web Store.
We believe strongly in the mission of enabling people to communicate with each other worry-free. We respect people’s inherent trust in choosing to link their accounts with our service, and take it extremely seriously. Period.
We provide universal message searching, just in case you aren't sure where exactly you had a conversation with someone. Also, for example, if you use one app to talk to someone for work, and another for personal stuff, our filtering allows you to put those in separate channels so that you can focus on what you need to, when you need to.
