In most cases, we suggest against sending your discount code by email to your customers. Experimentation shows that customers who leave your site to go to their email have a lower overall conversion rate.
That being said, if you know you'd like to make this happen, it is possible with Tada 🎉. We currently do not have the option to automatically send the email out through Klaviyo. What Tada does is that we pass the discount code to Klaviyo through an integration. That being said, the template setup and automation on Klaviyo's side needs to be setup in order for this to happen automatically (if desired).
We recommend reaching out to the Klaviyo Support team as they'll be more equipped than us when it comes to a custom Klaviyo template and automation that would integrate one of your custom variables, in this case, showing the discount code or coupon name to your customer (we pass the discount code through a custom variable to Klaviyo) in an automated email.
