Owning your domain is still good. Running your own mail server as a primary inbox mostly isn't anymore. The hard part in 2026 isn't SMTP, it's deliverability and reputation: Gmail now requires real sender auth (SPF or DKIM for all senders, SPF+DKIM+DMARC for bulk senders, plus PTR alignment), so a small VPS mail IP becomes an ops job fast.
