Papel de Parede

Please tell me how to create stationery in eM Client.

Templates can be created in Menu > Tools > Settings > Mail > Templates and Signatures. For more help, please see the help file (F1).

I tricked in the title of the message, I referred to wallpaper but wanted to even ask is how to create a “stationery”.

I think the term “stationery” was coined by another email client. In eM Client it is referred to as a Template. That means you can specify the default background, fonts etc. for new messages you compose.

Recebi um e-mail e gostaria de aproveitar o seu fundo (modelo) para futuras mensagens. 
Como posso salvar esse papel de carta (fundo do e-mail) para aproveitá-lo posteriormente?
