"collect customers responses" should be "collect customers' responses" (this error is repeated elsewhere, including a heading).
"All you need is just copy and paste" is as bad as "all your base are belong to us"; it should be something like, "You just need to copy and paste" or "All you need to do is copy and paste"
Capitalization of headings of the four blurbs is inconsistent.
"You can do the most necessary things for your customers at the moment." - this is very awkward. Which moment? You mean, "You can do the most necessary things for your customers at any given moment" which is still awkward. Perhaps better would be "Know what your customers want most at any given moment."
"The result is [...] growing business". That sounds like the result has a growth of business on it -- notice the similarity to "The result is growing moss". It should be along the lines of "The result is [...] a growing business". Even better: "The result is [...] business growth".
Your tagline "UserEcho - new way to listen and engage your customers" should be either "UserEcho - a new way to listen and engage your customers" or simply "UserEcho - listen and engage your customers". Additionally, it's impossible to "listen a customer". You listen to customers.
Yes, these things are small, but they matter. I can't take you seriously with such poor grammar -- it makes me cringe and want to leave the site, which I otherwise find really cool. I would consider using your site in the future, provided the grammar has been improved (it makes the site appear very unprofessional).
