Their landing page software is good but...
Their landing page software is good. However, they also run an agency to help maximize the conversion rate and will try to cannibalize your clients. Having said that, there is little benefit as an agency to recommend Instapage to your clients because they will try to push their agency services to your clients such as conversion rate optimization. Moreover, their price is really elevated, which doesn't make sense, because this would be the prime tool for agencies to manage multiple clients at the same time, but it's tough to want to work with the tool when they have sent blast emails offering their conversion rate optimization services to our clients... I do want to say their customer service is amazing, and the software is really good, but it's just sad to see that they're competing directly with such a huge segment of their clientele (agencies).
