I have been using Sunrise for about a month now and I love it.
Sunrise is a website that you connect with and in a matter of a few minutes you are all setup and ready to go.
From their website,
What are you doing today?
Sunrise combines Facebook, Google Calendar, LinkedIn and more into a nicely designed daily email.
And it’s free!
Basically, what happens is that you sign up and connect to the social networks that you wish to use. Then every morning you will receive an email in your inbox giving you the lowdown for the day.
The email looks like this when it arrives(I did not show the birthday section for privacy reasons.)
I have my Sunrise connected with everything including all my calendars
