Embedding base64 PNG in newsletter not possible

Hello Experts,
hello Christopher,

I have a question regarding the inclusion of graphics in newsletters (in my case, for customizing the subscription email). I would like to include my company logo in the footer of this email. To avoid externally embedded graphics not being displayed, I usually insert the logo as base64 (<img title="Logo" src="data:image/png;base64,iVBORw0KGgoAAAANSUh.......". However, even if I disable the editors and only use the HTML editor, the base URL is always prepended in the src of the email I send (img title="Logo" src="https://str.domain-community.net/data:image/png;base64,iVBORw0KGo........">
How can I prevent this?
Thank you and best regards,
Michael

Hello Michael and thank you for bringing this up.
We have fixed it and the fix will be included in the next release.

Just a note, Gmail doesn't support base64 images.

Wow, that's what I call truly amazing support! Thank you so much Christopher!
