heelo there

i just attempted to add a second email to my accounts…i sent a test email to the new email and it came back mail undelivered

the email address that was denied is…[email protected]

please advise asap

Check the email address again. Also, the message from Google will usually say why it was not delivered. 

If everything seems correct, you need to contact Google as this is not an issue with your email client. eM Client has delivered the message to the server, but the server is not able to deliver it to the destination.
