@Endriking I received a scanned copy of my certificate by email 4 weeks after the exam so I would say that it depends on the center where you take the exam. I took the exam on September 21 and received a scanned of my certificate by email yesterday.Usually it takes from 4 to 6 weeks to get the results. But eTEF gives the results for Listening and Reading sections immediately. All you're waiting for is Speaking and Writing.
No they don't email them. You wait for the final certificate which includes the certificate number and PIN.
