A common method of reducing unwanted email (‘spam’) is to change your email address. However, a recent court decision has shown the danger of doing this and leaving the old e-mail address unmonitored.
The question at issue was whether the sending of a notice by email to the former email address of the recipient could constitute a proper service of a document (in this case a notice of arbitration) if the email could be shown to have been received, despite the fact that the management of the business had not seen it.
In the view of the court, if the sender could demonstrate receipt, then the document was validly served.
If you change your business email address, you should have a system in place for ensuring that any correspondence sent to the old email address is monitored.
