What is the mail client with android "letter template" option?

Question

Android

Hi all!
The browser version of yandex mail has a very useful option - a letter template.
This is when a letter saved as a draft can be opened, edited and sent, while the skeleton of the letter itself will not go anywhere, but will remain in the "templates" folder for later use. Yandex by no means want to bring this useful option to their mobile client.
Tried k-9 mail. But in it you can copy the letter to the drafts folder, then edit and send.
Can someone tell me, before I dig up the Internet, are there email clients with a similar function?

Answer 1

They answered me:
In the current version of the application (4.5.0), you can use letter templates from the Templates folder. :)
So, you can download Yandex.mail for Android and use it.
