Fyl meaning in mail

A curious question!

In the context of email, "FYL" is an abbreviation that stands for "For Your Loss." It's often used in a humorous or sarcastic tone to express disappointment or frustration with someone's response or behavior in an email conversation.

For example, if someone sends a rude or unhelpful response to an email, you might reply with "FYL" to convey that you're not impressed or satisfied with their response.

It's worth noting that "FYL" is not a widely recognized or formal term in the email world, and its usage is mostly limited to informal online communities and social media platforms.
