You can enable event-triggered emails for your reward/referral program through Yotpo Loyalty. If your email provider integrates with Loyalty & Referrals (Klaviyo, Bronto, or Hubspot), you can set up these emails from your current email platform.
If your email provider does not integrate with Yotpo, you can enable event-triggered emails from the Triggered Emails section in your Yotpo Loyalty & Referrals admin.
You can learn more about customizing Yotpo Loyalty triggered emails here.
