I'm assuming you use something like Google Apps to handle your mail. If so, you can set up a "Group" called something like sales@company.com. You can then add each rep's individual email as a member of that group.

Any contact forms, lead generation forms, or materials should point to that email address. Any inquiries you get will then go to all members of the group, and you can manage who is responsible for which inquiry separately.

As an alternative, if you have a "Sales Manager" type role in place, just have sales@company.com go to you, and forward qualified leads to each rep in a round-robin. It takes more manual work, but would allow for an equitable lead spread.
