Manage blocked messages
When an inbox provider rejects your message for a content reason, this is called a block. This can happen for a few reasons:
- Someone added your mail server IP address to a deny list.
- An ISP blocked your mail server IP address.
- A filter on the receiving server flagged the content of your message.
The Block Reason provides the exact reason. You might have your IP address removed from a deny list. Some lists remove email addresses after a period of time. To correct a filtered block, you can modify message content.
Info
Unlike addresses on other suppression lists, Twilio does attempt to send messages to blocked addresses. The message content might differ and the recipient server might not block it.
You can filter your list of blocked email addresses using an address or date ranges.
To receive a notification for each block message, turn on Forward Blocked Messages.
- Open the Twilio SendGrid console.
- Go to Settings > Mail Settings.
- Click Forward Blocked Messages. The Forward Blocked Messages panel appears.
- Choose which email address should receive the notifications.
- Toggle Forward Blocked Messages Status to Enabled.
- Click Save.
To change the range of blocks displayed in this list, choose a date range.
- Open the Twilio SendGrid console.
- Go to Suppressions > Blocks.
- Click All Time. A calendar appears.
- Click the date when your search should start.
- Click the date when your search should end.
Your recipient list refreshes and displays the recipients blockd in that range.
To reset the date range to all time through the Twilio SendGrid console:
- Click date range button. A calendar appears.
- Click All Time.
Your recipient list refreshes and displays the recipients blockd for all time.
To download a list of blocks, export a comma-separated value list.
- Open the Twilio SendGrid console.

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