The most common reason for an email address bounce is that the address in question is invalid.
A bounce means that the receiving server has rejected the message, which means that LoLo will no longer attempt to send emails to this recipient’s address. This indicates that we have received a code signifying a persistent problem with either the server or the recipient's email address.
You’ll want to double-check the email address you have in your records, or update with a new address.
