Every account is personal, so we recommend that you provide a personal email address.
You can link your account (or have it linked) to multiple organisations and provide a contact address per organisation.
In other words, your Immo-Connect account is separate from the organisation(s) to which you are added within Immo-Connect.
If necessary, you can change your e-mail address in the "my profile" section of Immo-Connect, where you can choose the tab "My account".
Please note that when changing your e-mail address, you must activate it in the same way as when creating your account.
