# Selecting the Customer List

## How to Select Customer List for Broadcast?

There are two ways to select the Customer List for the broadcast:

1. **CSV Uploads:**

   You can upload a CSV of up to 2 Lakh users to create your customer list for the broadcast. To find the required format of the CSV, click on "Download Template" when you select uploading CSV as an option.
2. **Segments:**

   For Shopify Accounts, you can create segments of users with filters such as number of purchases, purchase dates, location, products purchased etc. Once you have created your segments, you can merge upto 4 segments and send them a broadcast at once.

## Best Practices

* Add customer properties such as First Name, or unique discount codes to personalize the final messaging which leads to higher engagement.
* Create segments that do not contain customers who made purchases in the recent past to improve your ROI.
* While creating your broadcasts, you can use location-based segments to send messages in regional languages or to target regions based on the festivals they celebrate.
* Use product-level filters to retarget users for cross-sell, up-sell, or re-order campaigns.
