Build customer trust by giving everyone in your company a professional email address at your domain, like priya@yourcompany and joe@yourcompany. Also create group mailing lists, like sales@yourcompany.

We recommend that you setup Google's G Suite. You'll get Gmail, Docs, Drive, Calendar, Meet and more for your business. The biggest benefit that comes with having Google manage your email is that their engineers are monitoring their email service 24/7 and you don't have to worry about your emails getting blocked because a server IP got put on an email blacklist.
