I ran surveys back in the day with little to no results that gave me no honest picture of what was going on. Maybe if you are a higher volume store and you had enough people filling out the survey, you might eventually get something that you could base some strategic action on.
If you want to increase your response rate to surveys, you might want to consider out sourceing it through a company like
Vital Insight Group OR build your own survey using another email/survey provider and only hit the customer after the purchase or 1 time after no purchase or contact. Have the survey look as if it's coming from a 3rd party or manufacture and don't use your own email address. It has to be professional and ask the RIGHT questions.
Mercedes-Benz went completely paperless a few years back with their CSI surveys and continues to use
Vital Insight Group with success.
TIP: I saw a huge climb in survey emails when I sent survey/support emails from an email like customercare@ OR mercedescare@ hondacare@ you get the picture...
An email a day for 30 days, I too find to be a little much...however, it's what you are saying, how you're saying it and what information you are providing to the customer that determines whether or not they will continue to read your emails or hit the delete button.
I wrote an article on DR about a year ago that drills into AIUA
4 Letters That Will Sell You More Cars This Month Attention, Interest, Urgency, Action that when followed..can make a difference in you email response rate.
Sorry to go off subject a little there but it's all about getting your emails read, personal email, marketing emails or even a survey.
