When you use the #Send an email action to notify #external email adresses, the from address looks something like @neu.workflownotification.com (probably depending on region). The problem with this, is that it often ends up in a spam folder of the recipient.
Is there a known solution to this problem using only Nintex? Can you somehow customize the source address?
I have a workaround that involves using Azure LogicApps but would prefer keeping it simple.
