A candidate who can't communicate effectively seems unlikely to be of interest to you, right? If their communications don't clearly tell you about their past experiences and skills relevant to your needs, I don't think you need to overthink this. When I am on hiring committees at my org, I always come up with a simple rubric to screen applicants and narrow down who we want to include in the process going forward. It is a very simple rubric, usually just "Yes/No" answers to questions related to the needs of the position. We can usually use these rubrics to stack rank applicants and interview top candidates. We do get some simply terrible cover letters or email communications from candidates (both native and non-native English speakers). These are usually so bad that the candidates in question don't get past the rubric anyway . . .
