Pricing and Cost Advice

"We pay for the license annually."
"The product is quite cheap."

"We do not pay for licenses to use this solution."
"Zimbra Collaboration is less expensive than Microsoft Exchange. Zimbra works for small companies because it is not expensive. Zimbra Collaboration has more security tools than Microsoft Exchange. If you are choosing between Zimbra Collaboration and Microsoft Exchange, you have to take into account the cost of security tools with Microsoft Exchange. When you purchase Microsoft Exchange, you will also have to purchase tools for security, which adds to the cost. The migration from Zimbra Collaboration to another email solution is very simple and easy. Migration from Microsoft Exchange to another email solution is very difficult. Microsoft doesn't allow migration that easily. In fact, you have to pay for tools to do that. You have to buy some expensive tools to migrate."

"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"The solution is competitively priced."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
