Just use a new email, doesn't have to be Gmail. Doesn't event have to be an email. Any random string is fine
There is an option to Delete your account from the in-game Options screen.(see pic below, asking you to confirm that is what you want to do)As for @Badabibidon above, the only way you are using the same email for 2 different game accounts is if one is via Kabam ID directly, while other one is via Play/Game Center account login.I’m assuming maybe the Kabam ID one is your original (as the WebStore uses Kabam ID login). And that you want to use that email (which is ALSO what you use for Play/Game Center) as direct Kabam ID for your 2nd account (? Which is maybe the one you only still play now ?)Deleting the 1st account via in-game options would clear it out from being attached to a Kabam ID.(*provided you still can login to game with that, and it is just all the other “verification” questions that you have forgotten some of the info for)Then (maybe after a period of time), you should be able to re-use it for creating an actual (new) Kabam ID to associate with your 2nd account.That should then let you use WebStore for that account.
As many have mentioned, it is a difficult task to accomplish yourself.Best to go thru Support now, and try and have them link your email to creating a Kabam ID for the remaining account.https://help.kabamsupport.com/hc/en-us/requests/new
