The Send Reply action sends a response to a specific Gmail message while preserving the original conversation. It addresses the original Reply-To header when present, otherwise the original sender.

​
Inputs

​
Outputs

The action preserves the original subject and builds reply headers from the selected message so Gmail keeps the response in its thread.
Reply All can notify every original To and CC recipient. Leave it off when a private response is intended.

​
Troubleshooting

The source message must have a subject, RFC message ID, reply or sender address, and Gmail thread ID. Confirm the Message ID points to a complete message in the connected mailbox.
Turn off Reply All to reply only to the original Reply-To or From address.
