Embed music in an email?

Can someone help me?

I'm looking for a way

when I email someone (gmx)

send, and the person who opens the email,

no matter whether via cell phone, PC, tablet, laptop, then a song is played.

Someone got an idea?

Helpeee

Would be super happy if you could help me.

Attachment brings me nothing.

greet all

stay healthy

No chance. Something like this is prevented by every email program because it is seen as a potential attack.

That will not do. Why is it not possible to attach files?

But then the person may have to open the attachment himself…
