what is the limit?

[Arnav-Kushesh]

how many emails can be sent per second and how does it works?

@itsarnavsingh - I haven't personally tried to push it to the limit so I don't have an accurate number for you.

Are you asking how the code works or how sending emails work?

@itsarnavsingh Not really answering your question, but I will assume that locally the code send mails very quickly. The limit you will reach is not local, but remote: emails servers will reject emails if you send them too quickly to avoid spam.
