How to Create a Company Email Address: From Primary Mailbox to Domain Setup
A practical sequence for choosing a domain, primary address, DNS records, and operating rules for a company email address.
Define the role before the address
A primary address should immediately explain why a customer should use it. Use clear role names such as contact or hello for general inquiries, support for customer care, and billing for invoices. An address based only on one employee creates unnecessary changes when ownership moves.
Use the same root domain as your website
Enter the root domain in the form yourdomain.com, without www or https. The www host is normally for the website; email uses the root domain. Your registrar and DNS provider may differ, so check the service currently authoritative for the nameservers.
Configure MX and sender authentication together
MX routes incoming mail. SPF declares authorized sending servers, DKIM verifies a cryptographic signature, and DMARC defines the policy for failed authentication. Testing only reception while skipping sender authentication increases the chance of Gmail rejection or spam placement.
Test in both directions after connection
Send from Gmail or another external provider to the primary address, then reply outward from the company mailbox. Review SPF and DKIM results in the message source. Finally, update the website, proposals, and contact materials to use the same official address.
Start with OfficialMail
Start operating with one official primary mailbox.
Use one primary mailbox as your company's official address and review every domain-connection value directly in the mailbox.
