I was hired to run a survey of members of a discount program with a large B2B company that operates an ecommerce website. They have a list of more than 100,000, which makes sending the invitations difficult.
This seems to be a grey area, spam-wise. Everyone on the list did sign up for the discount program, and most have made purchases over the years. The survey is about the discount program and the company. But a lot of the recipients would still consider the survey invitation to be spam, especially those who have lost interest in the company and no longer buy its products. (In compiling the list, the company can't tell who has tuned them out completely, and who just hasn't needed anything recently.)
I would appreciate advice on two dimensions:
-- technically, it's no problem for me to send the invitations myself over a few days, though one major ISP spam-foldered them from the start and I am getting resistance from another only 20% of the way into the run. How doable is it to get this sort of message delivered?
-- are there any reputable US-based services that would handle the email volume for me, and use their expertise to get best possible results?
