MySMS is a free web messaging platform that allows users to send SMS messages from a web browser without downloads or installations. It requires setting up an admin account to manage NeoGate TG devices and create user sub-accounts. Users can then log in to choose a device, enter recipient numbers or contacts, and send SMS messages individually or in bulk templates with personalized fields. The platform tracks message delivery status and provides applications for notifications, reminders, alerts, marketing campaigns, and confirmations.
