What is Appointment Reminder and how does it function? Appointment Reminder is a text messaging software that automates the process of sending messages, eliminating typing errors. It can be synced with various calendars such as Google calendar, Officer 365, Outlook, Appointment Reminder, Redtail CRM, and Apple iCloud. Users can also utilize the built-in calendar to create reminders for sending messages. If the software does not support the customer’s calendar, they have the option to bulk upload CSV files daily, which only takes a few minutes. All users need to do is set an appointment, and the software takes care of the rest. Additionally, the software offers customizable templates that can be adjusted to meet specific requirements. Alternatively, users can write messages from scratch if desired. The software also supports the automated sending of voice messages or the uploading of audio files.
