Hi GP.
You posted in our Pre-Sales forum from a user account that doesn’t have any purchases associated with it.
We don’t answer support questions for Events core/free or PRO add-on in the Pre-Sales forum (such as how to customize the email address, like you’re requesting).
If you made your purchase(s) through a different user account, please login to that account and then post in one of the paid forums.
Thank you for your understanding and thank you for using our plugins.

Regarding purchasing our PRO add-on, it’s an add-on to our free/core The Events Calendar plugin, which includes the Month View. The PRO add-on adds a Week View, Map View, support for recurring events, additional fields functionality, and more! But if all you need is a calendar with Month View, you could probably just use the free The Events Calendar plugin.
Last but not least, we have a pretty great Refund Policy so you can buy one or many of our add-ons and thoroughly test them.
I hope this helps! Let me know if you have any follow-up questions.
