Frequently asked questions
How do I use variables?
Write the variable in double braces: name for the first column, or a column number like 2 and 3. Each line in the data list is a contact, with columns separated by a comma.
Does the tool send the messages?
No, this tool only prepares the personalized messages in your browser. For actual bulk sending via the WhatsApp Business API, use the LetsBot platform safely and within Meta policy.
Is my data safe?
Yes, all processing happens in your browser and your contact list is never sent to any server.
