Freedom251 › SMS Appointment Reminder Software
SMS Meeting
What SMS Meeting is
SMS Meeting automates appointment confirmations and reminders by text, using Microsoft Outlook, Google Calendar, or connected business software. Its Microsoft-certified Outlook add-in supports appointments, regular meetings, and Microsoft Teams meetings. The Google-certified Calendar extension works with Google Meet events and can put the meeting link in a reminder. Templates can fill in details such as a recipient’s name, date, time, and place. For other systems, its JSON REST API supports scheduled or immediate sends, API-key authentication, and delivery-receipt webhooks. Connected systems can use reported STOP replies to halt non-essential messages to that recipient. The maker says data is hosted in the European Union and advises against including detailed medical, legal, or financial information in texts. Essential costs €7.50 per user per month, excluding VAT, and Pro costs €9.50 per user per month, excluding VAT; both require separately purchased SMS packs. A 14-day trial is available, but there is no free plan.
Who it suits
SMS Meeting suits SMEs, charities, administrations, and healthcare providers that want appointment reminders connected to Outlook, Google Calendar, or business software. Its API is also intended for systems such as management software, ERPs, and patient or citizen portals.
