Divorce via email

Q: My son and his wife lived together abroad. She got a baby but unfortunately died before birth. On the advice of a doctor, she came back to Pakistan for her treatment. After sometime, my son sent an email through his computer, and wrote the divorce to his wife's email address. Divorce without any witnesses and signature. Both would like to reconcile and patch up now. I would like to know according to Islamic Shari'ah that has talaq has taken place through email or not?
