A domain-based email address gives customers a consistent business identity and keeps company communication separate from consumer mail accounts. It also makes it easier to manage users, aliases and access as the team grows.
What to consider
Reliable business email depends on more than mailbox space. DNS configuration, spam filtering, authentication, backup or retention policies and account security all affect day-to-day delivery and trust.
Plan SPF, DKIM and DMARC carefully, use multi-factor authentication when available and document who owns administrative access to the email platform.
