DocuGen has a premium feature that sends generated documents to third parties from your own email address, say myname@mycompany.com:
https://support.docugen.io/hc/en-us/articles/15305889811090-Customize-outgoing-emails
Currently this feature only works when the user generating the document is the same person who set up the sender email address. If another user generates a document (using the same DocuGen settings and the same board), the email containing the generated document will go out from no-reply@docugen.io, not from the custom email that the first user specified (such as myname@mycompany.com.)
This idea would make it possible for DocuGen to send out generated documents using the custom email address (myname@mycompany.com) regardless of which user generated the documents.
