Follow up with event leads by postcard
When an event lead messages your WhatsApp number, let Notis capture the follow-up and send a postcard after you confirm the address and design.
Trigger
New Message Received
Triggered in real time when your WhatsApp Business number receives an inbound message from a customer (text, media, location, or contact). Delivered via the Cloud API webhook.
Action
Send Postcard
Tool to send a postcard via u.s. mail with specified recipient, sender, and front/back images. use after confirming recipient addresses and design urls. example: send postcard(to name='john doe', ..., front image='https://...', back image='https://...')
Why this helps
Promising event conversations are easy to forget once the event ends and the next wave of messages arrives.
- Turn selected inquiries into a tangible follow-up
- Keep address and artwork confirmation in the process
- Avoid maintaining a separate manual reminder list
Setup
Build it in a few focused steps.
- 1Connect WhatsApp and Docupost once in the Notis portal.
- 2Create an automation and tell Notis which event inquiries should get a postcard and what to confirm before mailing.
- 3Pick the WhatsApp New Message Received trigger.
- 4Choose where Notis should send run reports.
- 5Test with one real lead and confirm the address and front and back image URLs.
Questions about this workflow
Will Notis infer an address if the person has not provided one?
No. The Docupost action requires a recipient address. Have Notis request or flag missing address details before sending.
What design information is needed?
The action requires front and back image URLs. Provide the design URLs or ensure they are available before the send step.
Can the automation decide which inquiries qualify?
Describe your qualification rule in the prompt. The trigger fires for incoming messages, and Notis can assess their content.

Message Status Updated
Triggers when a WhatsApp message status changes. IMPORTANT LIMITATION: WhatsApp Cloud API does not provide a native polling endpoint for message status. Status updates are ONLY delivered via webhooks in real-time. This trigger cannot directly poll the WhatsApp API for status updates. This trigger will return empty results as WhatsApp does not support this operation. To track message status updates, you must: 1. Set up a webhook endpoint to receive status notifications from WhatsApp 2. Store the webhook data in your own database 3. Use a different mechanism to query your stored webhook data For more information, see: - https://developers.facebook.com/docs/whatsapp/cloud-api/webhooks
