Email stationery for Mac?

Apple removed all Mail Stationery support from Apple Mail several years ago. This depended upon certain hooks in the mail application to work, so no third-party will have access to modify Apple Mail. Other mail clients may support this, but I am not an authority on them.

Can someone recommend a third-party app to customize email that will allow me to pick background color, insert logo etc. Apparently Apple no longer offers that feature as part of its Mac mail.

Thanks in advance!

Apple leaves a trail of baffling when it removes time tested user features.
