[Website] Could we get aggregate notifications about MTXes on our watchlist?

Whenever there is a big MTX sale, this is what my inbox looks like:



Notice that there is, for some reason unknown to me, a delay between each of the watchlist messages. This means that, for half of the day, I keep seeing the "new messages" notification light up, only to see a notice about a sale that I already know is happening.

On the one hand, I like getting notified when some of the effects I have an eye on go on sale. On the other hand, this can get quite annoying for large sales. This is not even the worst it gets; and I don't have that many MTXes on my watchlist. I can only imagine how bad it could be for people with bigger budget than me.

Would it be possible, whenever a sale starts, to just get a single message like "6 items on your watchlist are on sale", with a full list in the message body?

Thanks! <3
