can I send email from a g Suite group?

I have many web servers that send email verification from different email origin. I'm using Gsuite but I don't want to create a new account for each website.

for example:

web01 - sends verification email from elad@gmail.com web02 - sends verifications email from elad2@gmail.com

1. I need the emails to come from elad@gmail.com and elad2@gmail.com
2. I don't want to create a mailbox for each email address
3. Should I use one inbox with aliases?
4. Should I use groups?

What is the best way

Thanks, Elad
