3. Select the contacts
Choose the recipients. You can send to contacts in your base, import from a .csv file, or add manually.
Select from contact base
Choose lists, specific contacts, or segmentation rules from your contact base:
- Click on Select contacts;
- Select the list, specific contacts, or segmentation rules;
- Once finished, click on Select and continue.
Import contacts
Upload a .csv spreadsheet with the contacts. Submissions with variables must be made via .csv. The file needs to:
- Be in .csv format, encoded in UTF-8.
- Have phone numbers in the first column.
- Include headers in the first row with the variables.
- Have one contact per row, in the DDI+DDD format.
- Be up to 120 MB.
Example: For "Hello {{name}}! Your appointment was scheduled for {{date}} at {{time}}", the file should have columns for Name, Date, and Time.
💡 Tip: See how to correctly create .csv files.
Once the file is set up:
- Click on Upload file;
- Drag and drop the file or select it manually;
- Associate the variable fields with the corresponding values, i.e., indicate what each field in the imported spreadsheet represents;
- Enable the option Analyze .csv file to review your file and ensure it is ready for use.
- Once finished, click on Continue broadcast.
Add contacts manually
Enter the numbers manually in the DDI+DDD+9 digits format, separated by semicolons:
- Click on Add manually;
- Enter the phone numbers;
- Click on Add contacts to complete the action;
Once the message content and recipients are defined, click on Next to choose when the sending will take place.
Send or schedule sending
Select one of the sending options to complete the sending process:
- Send now for immediate delivery.
- Schedule sending to set the date and time.
- Best sending time to send when your contacts are most active.
💡 Tip: Split the sending into batches, if necessary.
Message Queuing
Message queuing is a mechanism used to manage the sending and processing of messages. It occurs when the system places the messages in a queue, processing them in the order they were received.
In general, it is a way for the system to handle overload situations, where the number of messages sent is greater than what the system can process simultaneously. This mechanism helps maintain order and consistency in message sending.
How it works
- Message Queue: Messages are organized in a queue, waiting to be processed.
- Ordered Processing: Messages are processed sequentially, in the order they were received.
- Capacity Adjustments: During high demand, the system may temporarily adjust its capacity to process queued messages more quickly.
What to do during queuing
During queuing, there may be a slight delay in processing the messages. In this case, we ask that you wait a little longer until all messages are sent. The sending process will continue in an orderly manner, and the messages will be delivered as soon as possible.
