Specifying a technical contact
In your Account Information, you'll see an area where you can customize some contact details. The "Primary technical contact" is one of them. This is the contact to whose attention we bring any engineering-related problems. By default, we let all your account admins know.
If you specify a contact here, we can bring any technical concerns straight to their attention. For example, if there's an operational issue with your Customer.io setup, we can directly notify the person you think is best-placed to deal with it.
To do this, just change— and then confirm— the "Primary technical contact" email in these settings.
If you don't specify a custom email address (or leave the field empty), we'll notify all account admins.
