What's the Best Way to Notify Your Users?

Most of our, most of the competitions, whether you're looking at help des solutions or email products, they charge per user per month or per user per year. So i believe that people get more a benefit out of the product when they have more users. One trick that i've used that i think is successful is, for us, we have monthly subscription and yearly subscription. And so you can tell them that if they switch to a yearly plan, they will lock their price for one more year,. They pay less, you have the money up front, so at least that's one way to show that you care about them.
