An advertising firm with an e&o insurance policy sends an e-mail to alert the insurance agent of a potential problem. The advertising firm completed a large advertising campaign for a major client; the campaign is on the wrong product and cannot be corrected in time for the $100,000 advertising blitz. The agent takes information and tells the company to contact them when a claim is filed. Two months later the advertising firm switches insurance companies and six months later, the advertising company is hit with the $500,000 lawsuit. The new company says no coverage and the old company says no notification. Mistakes happen. Having an errors and omissions insurance policy provides protection to an insurance agent and the company.
