Quick question for the community In Anirudh's Email stack Training, he mentioned .com domains perform the best in terms of deliverability. I am setting up cold email infrastructure (mailboxes) for a client who owns a CPA firm in Canada. Their primary domain has .ca (which I believe is native to Canada businesses) Now I'm confused when purchasing subdomains for this client, do I opt for .com subdomains or .ca subdomains to setup the mailboxes? Appreciate the help!
