Natpest: Stop sending me emails every few minutes saying there's an unread statement in your webby SCIENCE's inbox. There isn't. I read it 40 minutes ago, after receiving the first 27 notification emails. (And very dull[1] it was, too.)
The email looks genuine, in as much as it's outsourced to mailjet.com. No phishy links, and it's got the last three digits of my account number[2]. I'm suspicious they're coming via a data centre in north west USAnia, and the filesystem's gone read-only due to the disk array being on fire.
[1] 'Dull' being the optimal state for bank statments.
[2] Interestingly, this is a joint account with barakta OTP, who isn't getting any notifications.
