How can we help you?

Upload a CSV file to send SMS campaigns to multiple recipients at once from the Compose & Send section of the ContactMonkey dashboard. Click here for steps on uploading CSVs to your Directory for reuse across campaigns.

Before You Begin

Your CSV file must meet these requirements:

• File format: UTF-8 encoding
• Phone numbers: E.164 format
• Column headers: Include PhoneNumber as the first column if you don't have email addresses

E.164 format explained: This international phone number standard ensures SMS deliverability. Format phone numbers as [+][country code][area code][phone number] with a maximum of 15 digits (example: +15555555555). Click here for a list of all supported countries.

Upload Your CSV File

1. In the Compose & Send section of the dashboard, click the CSV icon
2. Click Upload CSV
3. Browse and select your CSV file

Use the Sample CSV Template

If you're creating a CSV from scratch, consider using ContactMonkey's sample template to ensure compatibility:

1. In the Compose & Send section of the dashboard, click the CSV icon
2. Click it again after it displays the download icon
3. Open the downloaded file
4. Add your recipient data to the template
5. Save the file in UTF-8 format
6. Return to the Compose & Send page and click Upload CSV
7. Browse and select your CSV file

Note: The column headers in the sample CSV are suggestions, and the only mandatory field is PhoneNumber. If you only want to use PhoneNumber, it must be placed in column A of your spreadsheet.
