I like that it provides me with an email reminder about my appointment, as well as reminding others to reschedule their meetings if they can't attend at the original time due to another meeting or event taking place in our office space. Sometimes there is no notification sent out via SMS. A little glitchy but overall not too bad! We are solving all communication issues regarding clients who have scheduled business travel within 24-48hrs by being able to send them reminders through this serviceβ¦
