ExcelSMS is the most efficient way to send group messages. You can add recipient names and phone numbers in an Excel file. You can enter static or personalized text messages right in the Excel spreadsheet. For example, if you enter “Hi {first name}, ...” in a message, the app will take the first name of the recipients and personalize the message, generating text such as “Hi David, …” , “Hi Michael, …”…

You can use an Excel spreadsheet again without editing the spreadsheet on your computer. You can just pick an Excel file, type in a quick message and send it. It is similar to sending a message to a group.
