Id say cover letters should stay short anyway! My template is kind of like this: (Greeting), Thanks for considering (these pieces) for publication. (Any CRUCIAL information they might need to know about it). I have wanted to submit to (journal) after reading (recent piece) in (issue). Love what y’all do! Bio:: (Name) is (short bio). They’ve been recently published or are forthcoming in (max 4 journals— it’s not a CV). Thanks again, and looking forward to reading the next issue! Sincerely, (Name)
