⚡Message Logic & Limits
Understand how Dapta manages WhatsApp message dispatch, send windows, retry logic, and how Meta's messaging tier system determines how many contacts your campaign can reach per day.
Dapta text agent campaigns send WhatsApp messages through Meta's Business Platform. The rules that govern when messages go out, how many can be sent, and what happens when delivery fails are a combination of Dapta's own scheduling engine and Meta's account-level messaging limits. This page explains both.
Campaign Statuses
Every campaign moves through a lifecycle represented by its status. You can see the current status on the campaign list and on the campaign detail page.
Queued
Campaign created but the dispatch workflow has not started yet.
Running
Campaign is actively dispatching messages to contacts.
Waiting — Schedule
The current time is outside all configured send windows. Dispatch resumes automatically when the next window opens.
Waiting — Tier
The campaign has reached Meta's daily messaging limit for your account. Dispatch resumes automatically when the limit resets.
Paused
Campaign was manually paused. No messages are sent until you click Resume.
Completed
All contacts have been processed or the end date has passed.
Cancelled
Campaign was manually cancelled. Remaining contacts will not receive any messages.
Failed
An unrecoverable error stopped the campaign.
Waiting — Tier is a normal operating state, not an error. Your campaign will automatically resume once your 24-hour dispatch window resets with Meta.
Send Windows
The send schedule controls which days and which hours your campaign is allowed to dispatch messages. All times follow the time zone configured on the campaign.
Contact Days
Choose one of three options:
Every Day — the campaign dispatches seven days a week.
Weekdays (Mon–Fri) — the campaign dispatches only on business days.
Custom — pick specific days of the week.
Time Slots
Each active day has its own time slots with a start and end time. You can add multiple slots per day — for example, 9:00 AM – 12:00 PM and 2:00 PM – 6:00 PM.
The following rules apply:
Slots cannot overlap within the same day.
The start time must be before the end time.
At least one day must be enabled with at least one time slot.
If the campaign is running and reaches a time outside all send windows, it transitions to Waiting — Schedule and resumes automatically when the next window begins. No contacts are skipped.
WhatsApp Messaging Tiers
The number of unique contacts your campaign can message per day is not set inside Dapta — it is determined by Meta's messaging tier system, which is tied to your WhatsApp Business Account's quality reputation.
As of October 2025, messaging limits apply at the business portfolio level: all phone numbers under the same Meta Business Portfolio share a single daily limit.
Tier Table
Unverified
250
Default for new, unverified accounts
Tier 1
1,000
Meta Business Verification completed
Tier 2
10,000
Consistent volume at Tier 1 + quality maintained
Tier 3
100,000
Consistent volume at Tier 2 + quality maintained
Unlimited
No cap
Sustained Tier 3 quality with no policy violations
These limits count unique contacts per 24-hour rolling window, not total messages. Sending multiple messages to the same contact within a day counts as one toward your limit.
Quality Rating
Meta assigns a quality rating to your WhatsApp Business Account based on how recipients respond to your messages — primarily whether they block your number or report messages as spam.
High
🟢 Green
Messages are well received. Tier upgrades are possible.
Medium
🟡 Yellow
Higher-than-average blocks detected. Tier is frozen — no upgrades until quality recovers.
Low
🔴 Red
Significant negative feedback. Tier advancement is blocked. Account may be reviewed.
You can check your current quality rating and messaging tier in the Meta Business Manager under your WhatsApp Business Account settings.
Advancing to the Next Tier
Tier upgrades happen automatically — you do not need to apply or request them manually. Meta evaluates your account every 6 hours.
Unverified → Tier 1
Complete Meta Business Verification in your Meta Business Manager. Once verified, your limit increases to 1,000 contacts/day immediately.
Tier 1 → Tier 2 → Tier 3 → Unlimited
Automatic upgrades occur when both of the following are true:
Your account has used ≥ 50% of its current daily limit consistently over the past 7 days.
Your quality rating is Green (High) or Yellow (Medium) — not Red.
When both conditions are met, Meta upgrades your tier within approximately 6 hours. Under optimal conditions, a single account can advance multiple tiers within the same business day.
Tip: To climb tiers faster, focus on sending to opted-in contacts with personalized, relevant messages. Avoid blasting generic broadcasts — they drive blocks and suppress your quality rating.
What Drops Your Quality Rating
Meta downgrades quality ratings when a significant share of recipients respond negatively. Common causes:
High block rates — generally above 2–3% of recipients blocking your number.
Spam reports — recipients tapping "Report" on a message.
Template violations — using marketing-category templates for non-marketing content, or vice versa.
Frequency overload — sending too many messages to the same user in a short period.
Meta enforces a general frequency cap of approximately 2 marketing messages per user per day across all businesses. Exceeding this returns error code 131049. Dapta marks affected contacts and schedules a retry for the next dispatch window.
Retry Logic
When a message fails to deliver, Dapta follows a structured retry policy based on the failure type.
Transient error (network, temporary provider issue)
Retry up to 3 attempts total, scheduled at the next available send window.
Rate limited / daily cap reached
Dispatch pauses until the cap resets, then continues automatically.
Template paused or rejected
Contact marked Failed immediately — no retries.
Non-retryable provider error
Contact marked Failed immediately — no retries.
Once a contact reaches 3 failed attempts, it is marked Failed and skipped for the remainder of the campaign.
24-Hour Deduplication Window
To prevent accidental double-sends, Dapta enforces a 24-hour deduplication window per phone number per WhatsApp channel. If a message was already successfully sent to a phone number in the last 24 hours, any subsequent dispatch attempt to the same number is automatically skipped and logged as dedup_skip.
This applies across all campaigns that share the same agent channel.
