Even better will be when the Outlook add-on is available for sale, as people should be able to figure out that even if a very tiny percentage of Outlook users purchase Verb's Outlook add-on, the revenue would be significant. I'm not going to try and do any estimation, but anyone can go find estimates of how many Outlook users are, then take the very small percentage at a minimum they think will buy Verb's add-on, and multiply that by the monthly amount they expect Verb to charge for the add-on. It still can work out to a significant monthly revenue.
