Lots of services send me legitimate e-mails asking me to update my credit card information. I'm supposed to click on those. They come from Netflix and all of the text in the e-mail tells me to click on them. I don't click on them because I don't trust links from e-mails, but I'm supposed to.

No service ever sends me account verification e-mails for existing accounts. I'm not supposed to click on those. The text in the e-mail has instructions about whether I should click on it. This makes it different from the credit card e-mail.

You don't click because you're educated in these matters. Most people are not.

Not clicking on the credit card update e-mail requires being educated in these matters. Not clicking on the account verification e-mail just requires reading the e-mail before clicking. I think that's an important distinction.

Depends on the service. I've seen verification e-mails that just contain a link with no other text. Or with texts like "Continue here: [link]".
