At NFDC, we try our best to filter out junk email before it gets to you, but the battle against junk email is a losing battle. The only recommendations we can give, is to be selective of what companies you give your email address to and what mailing lists you sign up for.
You may also want to set up email filters, if you haven’t already. Filters will allow you to stop some of that junk email from being placed in your Inbox. Take me to email filters.
