Are you having troubles receiving email from the Naperville Area Chamber of Commerce?

Here are some things to try, please try them in order.

1. Add the sender to your address book. The email address the mail is coming from is chamber@naperville.net. This tells your email client that you are expecting mail from this address.

2. Whitelist the email address in your email client or internet security program. The instructions for this will vary for each person.
