When I post a job, I sometimes get up to 50 quotes and for each quote an e-mail. That's annoying.
It would be, however, I just had a look at the jobs you posted - the maximum number of quotes was 17...?
Is there a way to turn off the e-mail notification for quotes? If I want to see quotes, I can go the the quote list and don't need to get an e-mail each time somebody bids.
Currently, there's no way of turning off these notifications, and in fact, most job posters find them convenient. What you could do, of course, is to restrict jobs to Platinum members only - this tends to reduce the number of quotes received.
As an alternative, use a specific e-mail address only for the purposes of receiving job quotes/notifications.
