Clicks Aren't Being Tracked
Reasons why clicks may not be tracked:
Postmark maintains a block list. The blocklist is a hard-coded list of servers, domains and message ID's that we have expressly forbidden from allowing to use click tracking to disguise their spam. If a message is reported, we get an email from AWS. We then identify the abused domains, servers etc from the abuse report, add them to a blocklist.
You can paste an encoded link into https://click.pstmrk.it/decode and if the server or account is on a block list you will get "link_is_blocked": true in the response. Any blocklist removals should be discussed with Anna.
