Anyone here need to send email from your domain alias (G-Suite)?

Anyone here need to send email from your domain alias (G-Suite)?  In my case I badly need it. 

I have 2 brands, I would like to send email in pipedrive using my other brand. I have 2 domain, first one is brand1.com (primary domain) the second is brand2.com (domain alias).

I would love to be able to send email to my contacts in pipedrive using the domain alias as the FROM email address (randall@brand2.com).

I really hope this could be allowed because it's a pain to switch from pipedrive to g-suite (gmail) just to be able to send email from my domain alias. Plus I'll be missing out on the email tracking feature of pipedrive if I send from gmail.

Please! please! please! I hope Pipedrive can make this happen.

 I have a feeling a lot of users need this ability and most likely several have requested this as well.
