Does this site send rate alerts?

No, this site does not send rate alerts. The converter shows the latest reference rate and a 30, 90 or 365-day trend, and that is all: it does not send alerts, does not compare providers, and asks for no email address. Some banks and card apps offer alerts of their own. An alert only tells you that a level was reached; it cannot say what will happen next, and it does not change the rate your issuer or an exchange counter will apply, so check the real charge.¹
