Messaging from personal email address vs domain name address

[Harman N.]

Hi all,

I'm a new investor trying to get started with out of state investing. I want to begin making connections with out of state agents, lenders, property managers, etc should I use a personal gmail address? Or get a custom domain name, something like <FirstName>@<LastName>Properties.com?

It only takes a few minutes and costs a few bucks to get a G Suite account with a domain name, and would be more professional. I just don't want to come across as too hoighty-toighty given I'm a newbie. Or am I just over-thinking it?
