You can use personalization data sets in emails, mobile messages, and ladders.
After you've uploaded your personalization dataset, click the Copy Clip button and copy and paste the designated text in the pop-up into your email or mobile message. It should be formatted like this {{ your_clip_here | data_set | default: ''}}. We recommend filling in the default filter to account for anyone who does not have a value for the key you set. For example, voter registration might look like this {{ '6@!@state@!@211' | data_set | default 'Check your voter registration deadline <a href="https://website.com>here</a>.' }}
Make sure you test your personalization datasets thoroughly!
