Quick answer
You can upload an Excel or CSV file of numbers in the panel and send one message to everyone, or a personalised message using other columns.
Format your file
- Put mobile numbers in one column, as 10-digit numbers without spaces, dashes or +91.
- Keep one number per row and remove duplicates.
- Add columns such as Name or Amount if you want to personalise.

More questions
Which file formats can I upload?
Excel and CSV files are the most common. Keep numbers in one column as 10-digit numbers.
Should I include +91 before numbers?
Use 10-digit Indian mobile numbers without spaces or symbols, unless your panel asks for a country code.
Are duplicate numbers removed?
Remove duplicates before uploading so customers do not get the same SMS twice and you do not waste credits.
