I have recently created a send log and can see error codes

22,23 and 24

. I would like to know what these represent, as I have searched for documentation and cannot seem to find anything on this.

As usual, the documentation is very well hidden (here).

It appears:

22 (Data Extension Insert Failed) - Failed to insert a row into the Triggered Send data extension.
23 (Domain Exclusion) - The subscriber was excluded by a domain exclusion list.
24 (List Detective Exclusion) - The subscriber was excluded by List Detective.

Below is a screen grab of the chart, in case the link dies like they are prone to do...
