Option for open-tracking pixel in emails sent to use custom tracking domain.

We have a custom tracking domain configured for our sending domain.
Click-tracking links in outgoing email correctly use the custom domain but the open-tracking pixel in the same email still uses the default MailerSend domain.
From a deliverability standpoint this is a problem — the open pixel's host no longer aligns with our authenticated sending domain / DKIM and spam filters flag the mismatch.
We expected the custom tracking domain to cover both clicks and opens. Can we get a separate setting to route the open-tracking pixel through the custom tracking domain as well?

Hey Venetian yellow Condor, thanks for flagging this — totally understand the deliverability concern here. Appreciate you laying out the details; we’ll have the team take a closer look at getting the open-tracking pixel to use the custom tracking domain as well, and we’ll follow up once we have an update.
