Hi, Paul. Thanks for your interest in our plugin suite.
You might be able to customize things to not require an email address, but it’s not an option we offer. If you need some coding help, you may want to ask your developer or reference our documentation and list of known customizers.
Or you could do what you suggested with various dummy email address(es).
Last but not least, we have Bundles and a pretty great Refund Policy so you can buy one or many of our add-ons and thoroughly test them.
I hope this info helps. Let me know if you have any follow-up questions.
