I'm trying to figure out how to optimize the from address wrt deliverability and customer engagement. Haven't found much hard data on the topic.

Say that I have example.com as domain. Should I use info@example.com or set up newsletter@example.com that's exclusively used as the newsletter's from address? Are there any risks of using info@example.com in this context when I use the email addrress to handle all kinds of sales, support and b2b email?
