I tried a WP quiz builder last year and it was a nightmare to set up and get working properly.

I couldn't bring myself to pay for a monthly interactive Quiz and was so happy to find Quizify.
So far, so good!

Still figuring out if I can get it to score like I had in my WP Quiz, but it's already working so much better.

Thanks for making this product simple to use and affordable for those of us just starting out!

Edited to Add -- I found out the Quizify Lifetime Plan doesn't have the features I needed.
I learned from Customer Support that the AppSumo plans do not include Email Notifications unless you monthly fees. I didn't see that anywhere on the AppSumo Details, so I'll copy and paste in case this helps someone else decide if this plan is good for you.

From AppSumo Support:

For AppSumo plans, email-related features—such as customer emails or quiz result emails—are not included. These features are available only with our regular subscription-based plans, which you can view here: https://quizify.io/pricing. Unlike AppSumo, those plans follow a monthly or yearly billing model instead of a one-time payment.

We are planning to introduce email features for AppSumo users as well through a small add-on subscription. This is currently under development and may take around 2 to 3 months to go live.
