Send one SMS:

Send SMS in bulk:

To send SMS in bulk you construct a special CSV file. The only required column is phone. You include a template string that can include dynamic content, i.e 'Hi %{first_name}'. If you do include such content in the template we'll look for a column in the CSV-file with the name first_name.

⚠️ You need to escape '%' chars with '%%' otherwise '%': malformed format string - %! (ArgumentError) will be raised.

file.csv:

phone,first_name
+46735000000,Jacob

csv = File.read('file.csv')
template = 'Hi %{first_name}!'
StupidSMS.send_in_bulk(csv_string: csv, template: template)

full options:

csv = File.read('file.csv')
StupidSMS.send_in_bulk(
  csv_string: csv,
  template: 'Hello World!',
  delimiter: ',',
  dry_run: false,
  max_threads: 5
)

CLI

stupid_sms --csv testfile.csv --template template.txt --dry-run=true
