# Using a CSV contact list

> Send a stream of messages from the web portal to contacts in a csv format

## Create your CSV

You can have as many columns as needed in your csv for contact properties with the only requirement being
the contact numbers have the column heading `phone_numbers` and these are formatted in E.164 international format.

## Upload your CSV

In the web portal message composer click the upload button and watch the contacts populate.

Now you will have the valid contacts as destinations for your message.
