I have a workflow that creates a draft response to all of my Gmail emails.
It is working perfectly except that it is not creating the draft as a reply, it is creating it as a forwarding email.
It uses the right arrow and not the left (reply) one.
You’re experiencing a common limitation: when you create a draft via the Gmail node’s “Create Draft” action, it doesn’t automatically include the necessary In-Reply-To and References headers required to link the draft as a reply in the original thread
You can use the “Reply to a message” operation under Thread instead of a draft.
On the other hand if you want to create a draft (not send immediately), customize the HTTP request directly to Gmail API.
