Are there visual drag'n'drop editors for creating emails?

Question

PHP

Greetings.
There is a need to create functionality with which the user can create letters. These letters after sending must be valid in all popular mail services.
Are there any editors (albeit paid ones) in the form of libraries, by adding which you can create letters to the project not just by pressing a button to change the text style, but with ready-made elements (buttons, forms, lists, etc.)?
Thanks
