Thanks guys.
Casper. That's the route I want to go as well for purposes of scaling and not relying on another software.
I purchased some domains through GoDaddy. My employer uses Google Suite. I can likely request to get the domains added to Google Suite, but in the past, I was not able to connect to the Clay Sequencer when using a domain that was not the primary domain (tried OAuth and SMTP). I don't have Google Admin settings, so it's going to be a nightmare getting someone else to do this.
Does anyone recommend using a service like Porkbun or Zoho Mail to create these mailboxes and then tie that to Clay? My thought is I can just go ahead and purchase the Pork Bun email hosting, and then I'll have access to both the GoDaddy environment as well as Pork Bun and Clay.
