It only seems that recently, emails sent through this plugin through SparkPost now have their links set to “post.spmailtechno.com” which means that tracking open/clicks has been enabled. Links to this domain are (sometimes) treated as spam/ads and blocked by blockers.
There’s no setting in the plugin to control this. Is there a way to control this (hook?) and can it be incorporated into the plugin and deactivated by default?
You’re spot on. What you’re seeing is SparkPost’s click tracking feature at work, when enabled, SparkPost rewrites links in your emails to route through their tracking domain (in this case, post.spmailtechno.com). This is configured at the SparkPost account/sending domain level, not within the plugin itself.How to fix it right now
Log into your SparkPost dashboard → Sending Domains
Select the sending domain you’re using with Post SMTP
Look for the Link Tracking Domain section
Disable Click Tracking and/or Open Tracking as needed
Save changes
Once disabled at the SparkPost level, newly sent emails will no longer have links rewritten.
You’re right that there’s no UI toggle in Post SMTP for this. The plugin currently relies on the API configuration of whatever mailer you’re using.
(hopefully the image shows as you can’t add images to posts, only from URLs).
Our system default for our account is disabled for all APIs.
We also currently have 3 main plugins in use: Sparkpost (the old one), Post SMTP and WP Mail SMTP. Only Post SMTP is sending open/click tracking and showing these rewritten links.
