Biz Email & GoDaddy

I’m in the certification program but wanting to get some of my business set up before I start the entrepreneur track, so I can start making money sooner. I’ve found a domain I want to purchase and I know Brooke recommends getting a matching email address, but does she suggest we do that through GoDaddy or is there another vendor she prefers? I’ve been listening to the “How to Be A Life Coach” podcast, where she gives AMAZING recommendations, but I don’t think she ever said what vendors to use for an email address. Thanks!
