Messaging Limit on Campaigns
Meta limits how many new customers a business can start conversations with (template sends outside an open chat) in a rolling 24 hours. Kazenly shows that limit under Quality Rating and Messaging Limit and checks it when you preview a Draft or Scheduled campaign.
Customers you already messaged in the last 24 hours do not count again toward the limit for this check.
Where It Appears
Open Broadcasts → Campaigns, then open a Draft or Scheduled campaign (details / preview). The Messaging Limit card appears when your workspace supports the check.
While loading: Checking your Meta messaging limit…
Rows
| Label | Meaning |
|---|---|
| Daily Limit | Your Meta limit headline (for example 2,000 Unique Customers / 24 Hours or Unlimited) |
| Used In Last 24 Hours | Unique customers already started in the window |
| New Customers In This Campaign | How many list members would be new starts |
| Remaining | Capacity left before this campaign |
Notices
| Title | Colour | What it means |
|---|---|---|
| Within Messaging Limit | Green | Send fits under the limit (or the number is Unlimited) |
| Over Messaging Limit | Amber | Over the limit, but Start is still allowed — Meta may not deliver messages beyond your limit. |
| Over Messaging Limit | Red | Over the limit and Start is blocked — Start is blocked. Capacity may free up in N h / in N min / now |
| Messaging Limit Not Available | Neutral | Kazenly could not read the Meta limit — the campaign is not blocked for that reason |
When Start is blocked, the Start Campaign control is disabled. Tooltip: Over your Meta messaging limit — see Messaging Limit.
If Start Fails at the Server
The list may show an error such as:
Cannot start "…" — This send needs N new customers but only M of your L daily messaging limit remain in the last 24 hours.
Trim the audience, wait for capacity to free up, or review quality and opt-in practices under Settings → WhatsApp.
What Is Not Checked (Yet)
- Scheduled campaigns are not re-checked automatically at the scheduled launch time (v1).
- The card is hidden on older backends that do not expose the check, or when the messaging-limit gate is off for the workspace.
