1and1Mail now has three editions. For Free Edition, we have been offering the most powerful functions compared to all other email marketing software in the market. We, like you, hate to see a pop-up window asking for money every time you accidentally touch some advanced features. Instead, we simply set a limit on the number of emails you can send per batch. We firmly believe 1and1Mail can help you achieve more sales and acquire a much larger customer base. When your business excels with 1and1Mail, we would be quite happy if you purchase our Personal Edition or Business Edition to support your continuously growing business.
