Avoid email list delivery penalties that some Internet Service Providers (ISPs) apply to senders who repeatedly send to invalid email addresses.
Bounces
When you have email addresses in your subscriber lists that are no longer valid, they will bounce.
This is computer-speak for the “Undeliverable Mail, Return to Sender” error message. The
Manage Bounces page shows the newsletters or emails you have sent and how many email addresses have
bounced with each mailing. The reasons for bouncing vary. Hard Bounces are generally permanent. Soft
Bounces may be temporary.
Newsletter Name
You can click the name of the email newsletter or email marketing message listed in this column to
see a list of bounced email addresses and bounce error messages.
Sent On
The date the email newsletter or email marketing message was sent. If you have a late send or long
email list, this may be the date that the email finished sending.
Delete All
Use with caution. This command only removes the bounce messages without removing email addresses or
subscribers with invalid email addresses.
Export Soft Bounces
Use this feature to create a CSV file with all bounced email addresses except Hard Bounces. You can
save this file to your computer. To remove these address from your Subscriber Categories, go to My
Subscribers > Remove Subscribers and upload this file.
Export Hard Bounces
Use this feature to create a CSV file with all Hard Bounces – email addresses that we received
error messages from the mail server stating, “This address does not exist.” You do not
need to do anything special to remove these subscribers from your Subscriber Categories. All Hard
Bounce email addresses are automatically removed.
Message Removal
Bounce messages 21 days old or older are automatically deleted from the system at approximately
midnight EST/EDT each evening. My Reports > My Newsletters will
still keep track of the number of bounces, but the content of the error messages will not be
available. In most cases, this message content is not useful other than being able to distinguish
between soft and hard bounces, which our system handles automatically.
