My problem is that I need to distribute approximately 10 surveys in the next year to a participant base of about 1,000, and I don't want to spam them. I don't have the means to significantly increase the participant base, and surveys are probably the best method for my research.
My concern is the response rate will decrease as participants receive more survey requests, and people will feel like they're being spammed. The participants are also my company's customers, so we need to be careful in how communicate with them.
Thanks!
