I guess when you indicated your email address on your application form, CIC's main correspondence with you is your email. I didn't get a hard copy of the sponsorship approval. It was emailed to me. But I did get my hubby's passport back and a letter stating that they don't need the original passport this time but they made copies of it so it was being returned to me for safe keeping. I mailed the original, instead of just copies. Lol! But good thing, it didn't cause delay. I guess I'd be looking forward to all my emails. I even added my hubby's email on my mobile. Coz he rarely checks his emails. Lol!
