I had an opportunity to present last year at RTC North America with my BIM Manager. It was an awesome experience and we found ourselves in the top 5 speakers!
Our presentation was on Implementing a Building Performance Optimization Workflow. My portion specifically covered, speeding up your workflows with various methods which included Dynamo.
During my portion I mentioned that I use Dynamo for everything, including email!

At the time this was a bit of a dream, but we now have this ability in Dynamo with Rhythm! (and the python SMTP.lib) See this node in action below, (apologies for the sound quality)


I will be posting this nodes to the Rhythm today, so #GetRhythmForDynamo and have fun!
