The MacOS Bulk SMS Messaging Application allows users to send messages to national and international mobile networks. It offers the ability to manage and add multiple phone numbers in various ways.

First, I added the contact numbers to the recipient number list. This can be done by manually entering the contact number in the recipient number box or by importing a list from a txt file, excel file, or other sources. Next, I updated the message for each contact number using two different methods - either by applying a unique message to every recipient or by updating the same message to multiple contact numbers.
To control the load of bulk SMS transmission, I used the Delayed Delivery option to pause several text messages for a particular time. Additionally, the software allowed me to exclude blacklisted contacts from receiving messages using the Exclusion List Wizard option. I also saved a specific message as a template for quick access and use later on using the Save sent message to Templates option.
One feature that came in handy was the Skip Duplicate Numbers option that allowed me to skip repeated contact number entries while sending group messages. In addition, the software maintained the contact list during the sending process.
Lastly, the software allowed me to write the bulk SMS in any text format using the Unicode characters option before clicking on send option for the message transmission process. I was also able to export the text messages in various formats such as html, txt, or excel file formats.
Overall, I found this Mac software to be a reliable and effective tool for scheduling and sending text messages in bulk, with helpful features and user-friendly interface.
