Domain email standards
Clear definitions make adoption criteria clear.
Create official addresses such as contact@ or support@ on your company domain and configure MX, SPF, and DKIM.
01
An official address on your company domain helps customers recognize a trusted channel.
02
Review MX, SPF, DKIM, and DMARC to manage receiving and sender authentication together.
03
Start with a primary mailbox and expand the team and automation only when operations grow.
Domain email works when each DNS record performs its role.
Separating receiving routes from sender authentication clarifies which values to configure and why.
SPF
Add MX, SPF, DKIM, and DMARC one step at a time and verify their public status.
DKIM
Start with the primary mailbox and add member mailboxes when roles appear.
Connect domain email by checking the DNS flow in order.
Start in an order a small team can operate, then add features and accounts when needed.
Choose the domain and primary address.
Choose your company domain and primary address.
Find where DNS is managed.
Enter the guided DNS records and verify their public status.
Enter the provided records exactly.
Test with an external address, then publish the official address on your website and customer materials.
Verify the connection and test sending and receiving.

Owning a domain is different from operating email on it.
Business email is more than an inbox: it preserves records, trust, and accountability between a company and its customers.
Operational checks
Separate customer support, partnerships, and billing by address and folder.
Use company accounts so records remain when ownership changes.
If mail bounces or enters spam, review DNS authentication and the message authentication results.
