You can use Merge tags in Zoho Marketing Automation to get data directly from the default fields to your email campaigns. They can be used to personalize the subject line and content of your email campaigns with the recipient's data. For example, if you wish to begin your email campaign by addressing the first name of your recipient, you can use the '$[UD:FIRSTNAME||]$' merge tag.
"Hey $[UD:FIRSTNAME|Patricia]$, your order has been dispatched" would look, "Hey Patricia, your order has been dispatched".
