Can't remove "Sent from Mailspring" text

Hi, I’m using a Signature empty, but Mailspring sends the “Sent from Mailspring” text on the email.
Why does it happens? Thanks

Hi @sergiodevelop78,

I’m using the latest version for Linux (1.10.8-8ea2a61f) of Mailspring on Debian Trixie (Testing), and it’s working fine.
Which version are you using at this moment?

HI. I’m using Windows version 1.11.0-6.193b33c.
I have put the signature in pure html my own content, but still, at the end of the signature it is included in “Sent from Mailspring”.
