"lemme know" isn't passive-agressive, it's a clear request. you've got to sandwich the information you are providing inbetween two copies of the request:

- start with the request, so the recipient knows why they are reading the main content of the email before they start

- give them all the information that you can to help them respond

- and then end with the request again so it's clear what you actually need and they don't have to scroll back up to read it.

the request shouldn't be more than a sentence, so it's not significantly adding to the length to repeat it.

don't be shy about asking for a response - the whole point of an email should be to get a response, and being clear about what you need in the response is just helping your recipient. And if you don't need a response, be clear about that too - but if you're sending email that doesn't require a response, reconsider whether you need to be sending the email.

It's not a (sufficiently) clear request because it doesn't contain your recommendation. If you're asking them to provide their opinion, provide yours as well.

That e-mail should have been written in a style where "yes" could be a sufficient answer to the "lemme know" if the supervisor agrees, and currently it's not.
