I think it would be a great idea to have a user see a message after entering their email on a popup saying we recieved their email or thank you for subscribing.
Thank You message after form submission is available in Popup now! 🎉
This is where you can find this option:
Go to your widget Builder tab
Add Form block
Choose Submit Button section
Change Title and Text fields if needed
Feel free to test the widget out in our Popup online demo!
And don't hesitate to share your feedback in the comments 🙂
