What is pfb in email?

PFB in an email usually means 'Please Find Below'. It is a way to tell the person to look further down the message. They are pointing you to something, like a file you need to open or some text they have pasted in.

To be honest, it is a bit of an old-fashioned phrase. You see it more in formal or corporate emails. I reckon it is becoming less common. These days, people often just write 'I've attached the document' or 'You can find the details below'. So, it just means 'look down here for the information'.

Hope that helps a bit! Cheers.
