Mass Sending
The Mass blast Hablla's Mass Blast allows you to automate communications at scale by sending personalized messages, triggering smart flows and reaching your audience on the right channels — all in one place.
With this feature, you can send:
WhatsApp Templates: standardized messages approved by WhatsApp, ideal for campaigns and strategic communications.
Automation flows: execution of large-scale automations from a contact base (e.g., spreadsheets).
Messages for Webchat: sending communications via the integrated chat channel.

1. Creating a new blast
To start a mass blast:
Go to the menu Marketing > Mass blast.
Click New blast.
Fill in the initial information:
Blast name: set an internal title for identification.
Sending type: choose between Immediate send or Scheduled send.
Sending mode:
Single batch: sends to all contacts at once.
Split: divides into configurable batches, defining interval (minutes) and quantity per batch.
📌 Split sending is ideal to mitigate channel blocks and keep deliverability high.

2. Selection of the sending channel
In the next step, choose the channel:
Messages (WhatsApp) → use official templates and customize variables (such as name, company, agent, etc.).
Webchat → send messages to leads and customers active on the chat channel.
Automation flow → execute customized automations for each imported or segmented contact.

3. Selecting the audience
You can define recipients in two ways:
Spreadsheet
Import a file .xlsx with the contacts.
Each row executes a flow (in the case of the automation channel) or receives a message (on WhatsApp/Webchat).
Segmentation filters
Apply rules to select the target audience.
Examples of available filters:

Preview: watch in real time how the sent message will look.
📌 Example of a template:

I would like to schedule our first meeting to start the project.
5. Finalizing the blast

Click Finish.
The blast will be executed according to the configured sending type (immediate or scheduled).
You can monitor the results in real time on the performance dashboard.
