Text Formatting ⇒ Inserting an envelope icon in the corresponding author

[pythonet]

I have two questions:

First, I would like to insert an envelope icon in front of the corresponding author's name. Second, I have three authors all from the same institute. I would like to put the superscripts in the form of 1,2,3. How do I achieve this in Latex?

Attached image is what I want to achieve.

Thank you in advance

Without minimal working example I can only gamble with some general information.

Superscripts: → \textsuperscript

Symbols: → The Comprehensive LaTeX Symbol List

Thanks @Ijon Tichy

You answered my question. This is what I wanted exactly. Thanks once again.
