Review on Houston by Wayne Ohlrogge

We used Houston to build our waiting list and to collect emails for our email campaign. At first, they did a great job at building our waiting list. However, they weren't able to get many subscribers to opt in to our email campaign. They were also slow in responding to our emails. We had to wait a couple of weeks to get a response from them. If you're looking to build a waiting list, then you should consider Houston. They can help you get a lot of potential customers on your list.
