What Happens to Bad Mail Addresses?
> I was wondering what Lyris dies with bad email If Lyris is unable to send mail to an address it adds "1" to the person's bounce record. Once the number reaches 5, then that person is put on hold and mail will not be sent to
them until they are unheld. Depending on how your list is set up, held users may or may not be deleted after a specified length of time. You also have the option of periodically notifying users who
are on hold to give them the opportunity to unhold themselves. This is in the "List Settings."

Often, email addresses are not permanently bad. For example, juno.com sometimes has "mail quota exceeded" and bounces mail. But when the user clears their mailbox they are able to receive mail
again. So they may not reach the criteria of 5 bounces and are not held. This is the reason why Lyris looks for several days of bounces before holding people since many mail problems are temporary.
