Email is often one of the first communication channels between a business and its customers. Using a professional address on your own domain helps create a more consistent and trustworthy brand identity.
Brand credibility
An address such as name@company.com makes it easier for customers to identify the organization behind a message.
Centralized management
Business email platforms allow administrators to manage accounts, access permissions and security policies centrally.
Security
Business mailboxes are frequent targets for phishing, malicious attachments and account takeover attempts, making security controls especially important.
