Sender authentication is its own setup

Email sending domains establish the provider-authenticated sender used by supported campaigns and customer communication. A connected storefront hostname and its SSL certificate do not prove mail-domain verification.

Use a domain you control, a monitored reply-to inbox, and the sender identity shown by Brand Manager. Do not select someone else's domain or assume an arbitrary From address can be accepted.

Verify the records

Choose the sender domain
Open the email-domain setup for your developer brand.
Copy the provided DNS records
Use the exact provider records and record names. Preserve existing MX and unrelated records.
Verify
Review each required record and current verification status. DNS propagation and provider checks can take different amounts of time.
Preview and test
Check From name, verified email, Reply-To, footer, and links with an allowed test message.
Monitor outcomes
Review provider failures, bounces, complaints, and suppression rather than repeatedly sending to rejected addresses.
