Was 625 your original score?
Although you've gotten alerts in the past with 625 as your target, it works a whole lot better if you use your most recent known score.
Otherwise, check your junk/ spam e-mail folder. Also, go to your settings in SW and make sure that your e-mail addy is correct and current. If all this matches, call CS Monday (they're closed on Sundays), and ask if they can see why you didn't get an alert.
That's all I've got off the top of my head.

That's very true! Now that I look again at your screen name, I assume that you started at 566. If so, you've jumped 40 points since then, and that's wonderful!
Hope you can untangle what's going on with your reporting.
Most of the time, SW alerts work for most subscribers. But every now and then, it seems to go walkabout for some of us. It has happened to me in the past.
With luck, CS can find out what's going on. In the meantime, I strongly recommend setting your target to 606.
They really shouldn't call it a target score. 
(I think this is the hundredth time I've griped about this.) The way it works is if your new score "crosses" your target score, as in it goes either higher or lower than that figure, you'll get an alert. While I certainly see why any sensible person would pick a nice high figure as a target score, it won't work for alerts. I suspect that your previous alerts came from something else that SW picked up, something that fell under a credit alert instead of a score alert, like a new account, or a new inq, or a balance increase, or something like that. These all fall under the "credit alert" category, as opposed to the "score alert" category. SW checks for different things, and score changes is a separate category.
