With respect to the first part of your comment, I'd much prefer overcommunication of financial transactions about to happen and acknowledgement that they did rather than the other way about. And some communication about changes in Ts&Cs is often required. Those often come by physical mail. A lot of people here probably prefer more notifications about things like credit card transactions. I don't personally but many do even if it means a lot more routine email.
This is all well and good, if it can be turned off if set.
People used to find out about financial transactions monthly with their bill in the mail. It's fine to have more info, but that doesn't mean it must be forced upon us.
And the transactions described are not really out of the blue financial transactions. The first message is about transactions that happen every. single. month. There's no need to say "we're going to do what you want us to do". That's silly. An agreement was already signed to that effect. The person knows it's going to happen. It's just 100% wasted, useless info.
And while I know you're responding to the 'first part' of the post, the communication I'm describing in my (GP) post, is about just random emails with no actual value.
