"Typically, soft bounces are returned with an SMTP reply code in the 400 range. If Oracle Eloqua receives a soft bounce, it will attempt to resend the message for 48 hours in most cases. After that, Oracle Eloqua stops sending the message. The email address remains valid, and you can continue to send messages to this email address."
Does that mean that the mail will always remain softbounce and not consider hardbounce after 48 hrs?
Once an email is hardbounce will it always be considered hardbounce?
