Google has released two new tools: First is the “ROI calculator” that lets you see how much spam can impact expenses and productivity, particularly if your current anti-spam solution is waning in effectiveness. Once you quantify how much spam is costing your company, it makes sense to re-evaluate the IT options for managing spam. The first, and perhaps biggest, decision is whether to keep spam filtering in-house or use a hosted service. It can be difficult to add up the true expenses of each solution. On the surface, the cost of an appliance may seem reasonable, but the up-front costs are just the beginning in a complete cost-of-ownership calculation.

Secondly, To help you understand the whole cost of spam, TCO (total cost of ownership) calculator, which lets you compare expenses for in-house appliances versus hosted services. Using a three-year time horizon and considering both start-up and maintenance costs, companies can save thousands by choosing a hosted service.
