I am looking for a bit of clarity with regards to spam. I have a hosting client who owns a market research business. They have an australian travel company client who requires 10,000 of their existing customers to be contacted as part of the research project. I am still awaiting more info and have asked for opt-in details. It is a legitimate UK company who I have had many dealings with (they are one of the largest fieldwork based research companies in the UK). I was wondering if anybody had any suggestions on the handling of this? This would perhaps be best answered by any of the web marketing guys who may have been in situations like this themselves. Any constructive comments would be appreciated.
