Are there any limitations I should be aware of for broadcasts?
Configurations for broadcast campaigns may differ due to requirements and limitations imposed by the messaging channel you are using to send the broadcast.
For example, WeChat, SMS, and Telegram do not have “Read” message delivery status and you won’t be able to view any “Read” analytics for broadcasts sent via the mentioned channels.
How many broadcast messages can I send?
The number of broadcasts you can send is dependent on the usage limit of your plan and the messaging channel used for the broadcast.
You may refer to the "Plans and Billings" page to find the limit associated with your plan.
For broadcasts sent using WhatsApp channels, your sending capacity depends on the Business Portfolio messaging limit set by Meta. All phone numbers within the same portfolio share this limit.
The initial limit begins at 2,000 business-initiated conversations per rolling 24-hour period and may scale to higher tiers (10K → 100K → Unlimited) based on your portfolio’s messaging quality and recent activity.
Why did my broadcast fail?
If your broadcast fails to send, it may be due to one of the following reasons:
- Invalid or missing recipient data
- Messaging channel is disconnected or temporarily unavailable
- You may have reached your Business Portfolio’s messaging limit for your WhatsApp broadcasts, which temporarily stops outbound business-initiated messages until the limit resets or scales.
- Message content does not meet channel compliance requirements
-
Temporary system or network issues
How to troubleshoot failed broadcasts
- Check your Business Portfolio’s messaging limit: Your portfolio may have reached its current outbound conversation limit. You can resume sending once the limit resets or Meta scales your portfolio to the next tier. Learn more how to increase your WhatsApp messaging limit here.
- Maintain high portfolio-level messaging quality: Meta evaluates quality across all numbers in your Business Portfolio. A low quality rating may affect your ability to scale to higher tiers.
- Retry the broadcast later: If your portfolio is temporarily capped, try sending again after the limit resets. If needed, adjust your audience size so it fits within your portfolio’s available messaging capacity.

How long does it take for all the messages in my broadcast campaign to be sent?
The time it takes for all the messages to be sent for your broadcast campaign is dependent on the messaging channel being used as well as other factors.
For channels such as LINE Business and SMS, messages will instantly be sent after publishing your broadcast. For WhatsApp, messages are delivered progressively based on Meta’s throughput policies. Your sending capacity is determined by your Business Portfolio’s messaging limit, not individual phone-number limits.
You can expect SleekFlow to be able to send around 200 messages per minute. Please note that actual sending times may vary depending on factors such as:
- Peak usage periods - Broadcasts may encounter longer sending times when our servers are experiencing periods of high traffic and usage. These delays are temporary as we have mechanisms in place to handle peak periods.
- Network conditions - The time it takes to finish sending a broadcast to your selected audience can be affected by the network conditions between the user's location and SleekFlow's infrastructure, as well as any factors related to the user's internet service provider or regional internet performance. Additionally, this may be impacted when SleekFlow's server provider experiences service degradation or outages, which are outside of our control.
