Reply to Gmail threads from WhatsApp follow-up requests
Keep a conversation in its email thread when the next step arrives in WhatsApp.
Trigger
New WhatsApp Message Received
Polling trigger that monitors for new messages received in TimelinesAI WhatsApp chats.
Action
Reply to email thread
Sends a reply within a specific gmail thread using the original thread's subject, requiring a valid `thread id` and correctly formatted email addresses. supports attachments via the `attachment` parameter with valid `s3key`, `mimetype`, and `name`.
Why this helps
Follow-up instructions are scattered across chats, and replies can lose the context of the original email thread.
- Keep replies attached to their existing Gmail conversation.
- Use the requested follow-up details from WhatsApp.
- Avoid guessing which thread to reply to.
Setup
Build it in a few focused steps.
- 1Connect TimelinesAI and Gmail once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it.
- 3Tell Notis: When a new WhatsApp message requests a reply to an email thread, reply in Gmail only if the message or available context identifies an accessible thread and provides the reply content; otherwise report what is missing.
- 4Pick New WhatsApp Message Received as the trigger and choose where run reports go.
- 5Test with one real example and verify the reply appears in the intended Gmail thread.
Questions about this workflow
Can Notis find a thread from a vague description?
The prompt should require an identifiable thread and should not guess when several threads could match.
Will the reply remain in the original conversation?
Yes, the Gmail action replies within the specified thread.
