Hi Manychat team,

I face a problem with a small but consistent percentage of WhatsApp users and would like you to consider a new feature: Currently, there's no way to automatically identify and handle contacts who didn't receive a WhatsApp message due to:

a) WhatsApp-ID subscribed via API does not exist
b) temporary unavailability
c) Meta's delivery restrictions.

Suggested solution: Implement an automated system in Manychat that can detect undelivered WhatsApp messages, flag affected contacts, trigger specific automations based on delivery status, and provide options to retry sending messages or remove opt-ins if desired. For example a connector in flow builder like the one for user input "user did not reply within x minutes" --> "contact did not receive message within x minutes"
So I can followup with a normal action block and guide users another way through the automations at points of interest within flow builder. "

The benefit would be for the community, all WhatsApp Chatbot creators, agencies, agency-clients and WhatsApp users likewise. 

Use case: We run ads that subscribe contacts via API to WhatsApp and leads get their first message template immediately. For leads not reachable I need to notify an Admin, so they can call the person in time. Or send an API call to my CRM-System or Update a Google Sheet and so on… 

Use case #2: We subscribe gym members with their checkin via API to Manychat. If there are any problems, sending our initial welcome message, we need to know about it automatically to set further actions. 

Use case #3: We subscribe user via API after appointment bookings for confirmation and followups. If the contact is not reachable, we need to know about it to chose other ways of communication. 

A solution would help maintain cleaner contact lists, improve overall message delivery rates, and allow for more targeted follow-up strategies. It would save time on manual list management and improve engagement rates.

Thank you very much for your consideration :-)

Best regards
Sebastian
