Draft Reply - Learn WorkflowDog

The Draft Reply action prepares a reply in Gmail without sending it. It keeps the original subject and conversation headers, so a reviewer can finish or send the response from Gmail.

Inputs

Third-party account	Google account	Yes	Gmail account that owns the draft.
Message ID	String	Yes	Gmail ID of the message being answered.
Reply All	Boolean	No	Include original `To` and `CC` recipients except this account.
Body	String	No	Draft reply content. Defaults to empty.
Body Type	`Plain Text` or `HTML`	No	Body encoding. Defaults to Plain Text.
Attachments	List of files	No	Files to attach to the draft.

Outputs

Output	Type	Description

When Reply All is enabled, the finished draft includes original To and CC recipients other than the connected account. Review the recipients before sending.

Example: human-review support reply

For a human-review workflow:

Use the incoming email to generate a suggested response.
Connect the original Message ID and suggested response to Draft Reply.
Notify the support agent after Gmail creates the draft.

Troubleshooting

The draft is not threaded

Supply the Gmail Message ID for the message being answered. The action needs that message’s thread and RFC reply headers to construct the draft.
