Good to know

  • It is normal for bounces to occur, but the Oracle Deliverability Operations team recommends the following thresholds:
    • Hard bounce rate: 2%
    • Overall bounce rate (soft and hard): 5%
  • Bounces are returned from the receiving mail server with an error code (for example, 5.4.1), a reply code (for example, 540) and a descriptive message. Not all bounces include both the error code and reply code.
  • This report displays up to 1,000 rows per page.
  • Typically, soft bounces are returned with a reply code in the 400 range. Hard bounces are returned with a code in the 500 range.
  • Mail server administrators can customize the message that accompanies a bounce.
  • A detailed explanation of bounceback codes can be found at RFC 3463. Here are details provided by some ISPs about their error codes:
