Using Make.com unlocks the power of 1,900+ integrations to trigger journey automations and send automated WhatsApp templates to contacts saved in these systems. With this new capability, businesses can now start using automated transactional (proactive) WhatsApp messages (with open rates of over 90%) instead of traditional transactional emails (which have open rates below 30%). This enables businesses to send outbound messages at key customer touchpoints, such as booking confirmations, order receipts, tracking updates, or review requests.
