I too would like to see the option to toggle various emails and opt-out when desired. (New Bid, Your Bid being placed, You've won, Just Sold, Now available for purchase) each of these could stand to have seperate toggles and some could use even finer controls. For example, Just Sold emails seem to show on auctions I participated on but didn't win as well as domains I personally won and sold. The first is of little concern and the second I would like to know about. Another example, New Bid emails seem to show up on domains I have bids on regardless of them being on my watchlist or not. If they're not on the watchlist I likely don't care if I was outbid.

Those examples are perhaps just my personal preference and not a widespread sentiment but it never hurts to have such options if they can be added as well and I may desire those emails later so it's helpful to have the option to toggle them selectively and with such granularity.

Likely there are other emails that could warrant a toggle category/sub-category of their own as well but these were just the ones that came to mind. I would happily welcome more toggles if you find there could be more :)

please, provide various options [levels\degrees] for email optOUT!
