We recommend adding a second email address to your billing account. The reason is that we mostly provide technical and billing support via email. If, for whatever reason, the primary email address on your account isn’t working then we can always communicate with you via the second email address.

You can add a second email address as follows:

  • Log into your billing account at billing.catalyst2.com.
  • Click on your username (top-right corner).
  • Select Contacts from the drop-down menu.

Alternatively, you can use this link:

You need to complete all the fields (only the Company Name is not required).

If you also want us to send invoices and other emails to the second email address then you can tick the relevant boxes under Email Preferences. And in case you are wondering, no marketing will be sent to the new contact address.
