I logged into my blockchain and clicked backup and I chose e-mail backup and it said something like e-mail sent. but I did not receive any e-mail. i check my spam and all folders. my account shows my e-mail was successfully verified when I opened the blockchain account. I have cox.net e-mail. does my cox.net ip provider possibly block e-mails? also, what does backup to e-mail mean. does that just send me an e-mail with my blockchain account info in case I ever get locked out of my blockchain account. is there a better backup method than e-mail?
