Hi folks,
Great news: this scenario now can be supported with the help of our Popup app!
Recently, we have implemented the Autoresponse option, which lets you send auto-replies to your customers. And since you can customize the text, you're welcome to add a coupon discount there 🙂
Learn more about this feature on our forum: https://community.elfsight.com/t/contact-form-form-builder-subscription-form-popup-autoresponder-option/7928
Cheers!
