A WhatsApp session message is any free-form message a business sends to a customer within the 24-hour service window opened by the customer’s most recent message these messages are free of charge and require no template approval from Meta.
Session messages are the ‘free zone’ of WhatsApp business messaging. The moment a customer messages a business whether by replying to a marketing template, clicking a Click-to-WhatsApp ad, or sending an unprompted question a 24-hour session opens. During those 24 hours, the business can send any content (text, images, voice notes, documents, buttons) without restrictions or fees.
This is why response speed matters so much economically, not just for customer experience. A business that engages a customer the moment they open a session can have a full conversation, answer questions, send a payment link, confirm the order entirely within the free zone. A business that replies 25 hours later has to use a paid template message just to reopen contact.
