Well... in short, it depends.
I wanted to get a handle on basic industry preceptions in realtion to an area I am studying and wanted to get access to a wider audience, as using email surveys tends to deliever a very low level of responses and thus response rate.
Who are you going to be performing a survey with? When you state non-response bias, what are you assessing that against?
Response rates from surveys are typically pretty low. One thing you can do is compare the companies that did respond to the companies that did not respond. So if the "typical" subject that did not respond is similar to the subjects that responded, you might be OK.
If you find that a majority of the companies that responded are large mfg., and very few small service providers responded, you will have a difficult time generalizing your results over a broad organization structure.
Also, I hope you have done a field survey, focus groups, validation and reliability studies, etc. on your survey. If you are going to do it, it needs to be good.
That said, calculate what your non-response rate is. Compare to equivalent studies to yours. If your rate is the same/ lower, quote their study to give your results some strength. Compare the non-responders to the responders and determine if there are significant differences. And as always, increase how many people conduct your survey. Increased sample size helps.
