Here is my actual workflow set up.
I have two workflows acting on the same document library:
1) starts when an item is created and message is sent out to the user that an item is created.
2) starts with a condition, where if the document in the root of the library is updated and sends an email that a document is updated.
For both workflows, I use SharePoint user groups for the recipient field.
Since these are two workflows acting on the same library, is this the reason why Nintex is sending two emails? please help!!
