Email from account@nest.com not received or received too late; email from Washington post newsletter not received

Same exact problem. Can’t log on to Nest app, it says it sent authentication code to my @cox mail and code is only valid for 5 minutes. I get the code eventually hours later from account@nest.com but it’s way past the 5 minutes. 

troubleshooted with 5 levels of support of Nest. We added @nest to cox whitelist. Created rule in cox webmail to allow Nest domain emails in inbox, no luck, Same problem. 

Nest says this needs to be addressed by Cox, that their automated 2 form authentication is working fine and email generates right away and it’s sent, however cox is not allowing it in right away. 

can null help please???

Thanks! 

Am able to login; not receiving the Nest emakils with verification codes.As others have noted, Cox and Nest explain that the other is the source of the problem. Absent phone support, Cox is unable to speak with Nest. Sent email with source info to both tech supports- no response as yet.

Call whomever is administering your email servers to ask if the queues are backed up.  Don't be shy about posting the results of your "investigation."

Thanks Dustin. just emailed you the info.

Thanks

Same issue here.  Nest claims it is cox.net not delivering the email.

Same here

nest says they have no delay in sending it, it is a problem from your end. 

Latest Nest response: With the previous information, investigations on our end have determined that messages are being blocked by cox.net with a response of CDRBL which is explained on Cox's support site and will need to be resolved by Cox.

Appears that Cox is using cloudmark.
