What error 131049 means

If you send a marketing template through the WhatsApp Business API and get:

This message was not delivered to maintain healthy ecosystem engagement.

with code 131049, Meta chose not to deliver the message to protect the recipient's experience.

This does not mean your account is banned, your number quality dropped, or Interflow failed. It is Meta's per-user marketing template limit.

Why Meta blocks with “healthy ecosystem engagement”

Meta limits how many Marketing messages a WhatsApp user can receive from any business in a period, especially when they are less likely to engage.

The limit is adaptive and considers factors such as:

Recent marketing read rate
How full the inbox already is
Overall engagement with business marketing

That is why the error can appear:

After several recent marketing messages (from you or other businesses)
Even on your first send — the limit belongs to the recipient
When there are too many retries to a user who already hit the limit

What happens in practice

Situation	Result
Delivery	Message does not arrive
Webhook	Status `failed` with code `131049`
Immediate retry	Usually fails again
Other customers	Sends to other numbers usually still work
24h window	If the customer replies, marketing inside the window does not count toward the limit

An HTTP 200 on send is not proof of delivery — always check the webhook status.

How to resolve it

Wait at least 24 hours before resending the same marketing template (Meta's official guidance)
Do not retry in a loop — repeated attempts can extend unavailability for that user for up to 24 hours
If the content is genuinely utility or authentication, use the correct category (Utility / Authentication) — do not relabel promo content as utility just to dodge the error
Ask the customer to start the chat or reply, opening the 24-hour window
Segment campaigns toward engaged contacts

How to prevent it

Space marketing sends to the same contact
Avoid cold mass blasts without engagement
Keep opt-in hygiene and template quality high
Monitor 131049 failure rates in campaigns

Quick difference: 131049 vs 130472

Code	Message (summary)	Idea
131049	healthy ecosystem engagement	Adaptive per-user marketing limit
130472	user's phone number is part of an experiment	Recipient is in a Meta experiment

Both mainly affect marketing and do not mean the account is banned. Full details for both errors are in WhatsApp Business Errors.
