You can add recipients to a new Sequence by uploading them in a .csv file with the following format:
The header of the first column must be named "email". There can only be one column with this name, so you'll want to make sure your other columns are called something else.
Every row beneath the "email" header must contain a recipient's email address.
Additional columns may be added for Sequence variables, such as a recipient's name.
Here's an example of how a properly formatted CSV should look if you wanted to include your recipients' first name along with some other details.
To help you get started, you can download a CSV template below and add your own recipients and Sequence variables.
