@csoares93, looking at GitHub there are quite a few activities that can help you send emails. While I've not tried any of them myself, here's a non-exhaustive list 😃:
I searched Github for "flogo AND email language:go"
Some Flogo stats
204 distinct authors of activities. The author is the owner of the repository (either a user or an organization) where the activity is found. This isn't always the actual author of the code.
Based on a unique source location (unique GitHub URL), there are 932 activities, 299 triggers, and 307 contributions built with the new contribution model
With a total of 1538 contributions in the current database, there are 856 unique names (687 of these have been built with the old contribution model and 213 have been built with the new model)
Of those 856 contributions, 613 have version 0.0.1, and there is 1 contribution with version 220.127.116.11 (the latter seems to be the Couchbase activity)
The number 1 author, not being TIBCOSoftware or project-flogo, is @jvanderl
As I'm building a better way to search and visualize contributions over GitHub, I've created an Airtable which you can also use to search for specific contributions (like email or EMS)
These stats have been made possible with the Active Albatros release of FDIO
