email question
 

In a list of email addresses, can I format like this:
Brian Casey <bc@gmail.com>,
George Bigguy <gb@gmail.com>,
and so on.

I'd use no formatting at all if it was recommended:
bc@gmail.com, gb@gmail.com,

I don't care what method I use, I just want to follow modern standards. Of which I know nothing, obviously.

A little context would be nice. Where is this list, in an email app, on a web email app? totally depends on what you are using the list for.

FWIW, 2 email clients I used - Thunderbird and Evolution - use this format in the To/Cc/Bcc fields when composing a new message.

Both of those constructs are acceptable. I generally don't to the Real Name <email address>, but that's mostly 'cause I'm lazy. Contacts in email clients usually do use that format, however.

Either is "standard"

Thanks. This is fine.
 

Sorry didn't provide any context. This email list is written in VIM.

You mean you constructed the list in vim... which is fine, but not really relevant.
what we need to know is how you want to use it and which tool / service is ingesting it?

It depends on the E-mail client (the MUA) you're using.
some will accept only the pure user@email.address form,
others both your form (with <>) or the opposite way:
user@email.address (first lastname)
so with () and the two parts switched around.
For instance my alias list for "mutt" is in the form with ()

I tried the form with <> at WeTransfer.com and that site didn't accept it.

What was he solution?
