How to consolidate email accounts between different sales staff?

You need a CRM system that manages incoming leads. I am a beta tester for Salesformics.com and Stewart there will give you an awesome walk-through.

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.

I believe you can use Gmail for this purpose. Log into the Gmail account from which you would like to forward email. You will learn the workflow of how to merge two Gmail accounts into one inbox. In the secondary Gmail account, click the gear icon to the right and select Settings. Locate Gmail's settings. Locate Gmail settings. A popup displays reminding you that Gmail is verifying your forwarding Gmail address. Gmail sends a verification email to the primary email address entered. Connecting the two accounts in this way will allow you to quickly switch back and forth between accounts during the confirmation process without logging in or out. Connect two Gmail accounts to make switching inboxes easier. In the confirmation email, you will find a confirmation code and confirmation link. Enter the confirmation code in the Forwarding and POP/IMAP tab in the secondary Gmail account, or click the confirmation link in the email. Gmail prompts you to confirm that mail will be forwarded.
