Manage bounced messages

To receive a notification for each bounce message, turn on Forward Bounce Messages.

1. Open the Twilio SendGrid console.
2. Go to Settings > Mail Settings.
3. Click Forward Bounce Messages. The Forward Bounce Messages panel appears.
4. Choose which email address should receive the notifications.
5. Toggle Forward Bounce Messages Status to Enabled.
6. Click Save.

Note: If you enable bounce notifications, any interactions with the bounce notification (such as opens or clicks) are tracked and associated with the original message that failed to deliver.

To change the range of bounces displayed in this list, choose a date range.

1. Open the Twilio SendGrid console.
2. Go to Suppressions > Bounces.
3. Click All Time. A calendar appears.
4. Click the date when your search should start.
5. Click the date when your search should end.

Your recipient list refreshes and displays the recipients bounced in that range.

To reset the date range to all time through the Twilio SendGrid console:

1. Click date range button. A calendar appears.
2. Click All Time.

Your recipient list refreshes and displays the recipients bounced for all time.

To download a list of bounces, export a comma-separated value list.

1. Open the Twilio SendGrid console.
2. Go to Suppressions > Bounces.
3. Click the gear icon.
4. Click Export CSV. The file downloads through your browser.

To remove a recipient from the bounce list, find the recipient and delete their entry from the list.

1. Open the Twilio SendGrid console.
2. Go to Suppressions > Bounces.
3. Choose if you want to delete certain bounces or all of them.
   • To delete all bounces:
     1. Click the gear icon.
     2. Click Delete All.
     3. When prompted, click Delete.
   • To delete some bounces:
     1. Select the checkbox next to the recipient name that you want to delete.
     2. Click Delete.
     3. When prompted, click Delete.

After you remove a recipient from the bounce list, Twilio allows you to send email to that recipient. The bounce list doesn't include unsubscribed recipients.

Bounces occur either before (synchronous) or after (asynchronous) the message gets delivered.

• When Twilio SendGrid accepts a message for delivery, but the inbox providers reports that message as a bounce, an asynchronous bounce occurs.
• When the remote inbox provider rejects the message during the initial delivery attempt, a synchronous bounce occurs.

• Global Unsubscribes
• Group Unsubscribes
