What should I do about this person in my Intro Judaism class?

I'm thinking of sending this email to someone in my Intro Judaism class:

Subject: Request for No Further Contact / Request for Limited Communication

Hi [name],

I am reaching out to address the fact that you have been incessantly making unsolicited comments to me about personal and religious matters, including:

- How I should or shouldn't travel to synagogue on Shabbat.
- What I should eat to align to (your) kosher standards.
- How often I should be attending services.
- The times I should wake up on Shabbat.
- The amount of work I should be doing.
- How much money I should be earning.

Most recently, you found my email address - despite me never sharing it with you - and sent additional unsolicited “advice”.

I have no interest in engaging in conversations with you. Thank you for your understanding.

I could also just avoid him. Advice on handling this situation?
