In order to change your login email address, ReachHero requires an email sent from the email address, that is currently linked to your account for data protection reasons.
In this email, you mention the e-mail address, which should be used as the new login e-mail address in the future. ReachHero then changes the email address in the system and notifies you, once it has been changed.
Now you can log in with your new email address.
It is not possible to change the old e-mail address without sending an email from the old one to us.
