How to send pdf to email from laptop?

I have a scanned form saved as a PDF on my laptop and I need to email it to my landlord today, but I’ve never actually attached a file before. Where do I even start?

had the same thing last month when i needed to email a checklist. open your email app or gmail in the browser. click compose then the attach button (paperclip). find the pdf on your laptop and attach it then send. fwiw super easy once you do it once.
