Hi all,
We're using Brevo to send emails now and they add the tracking pixel. This happens also when you use their SMTP server and not their special templates.
Side effect is that they also send the email as HTML. I will see if I can force SMTP emails to be sent as plain text without a tracking pixel.
For the record: we are not using the tracking pixel for advertising purposes. It's purely so we know if the email was delivered and if it was opened so we get some idea how often people actually read these emails.
Cheers,
Johan
