Best Practices for Using Branded Email Domains

Using email addresses branded with your company domain name can help recipients recognize your organization as the sender, improving deliverability. However, care must be taken to ensure that bounce notifications are processed correctly. Review these recommended best practices when using branded domains to send mailings.

1. Keep the mailbox configuration provided by Oracle—At the time your site was created, an Oracle representative probably helped configure your Outreach mailbox settings using a mail account with an Oracle domain, such as rnmk.com. These settings should be left as is to ensure bounce errors are processed. See Email Bounce Handling.
2. Customize the message header—When creating the mailing message, add your branded email address by customizing the message header. Customizing the message header does not affect bounce processing, but contact replies to your email will be sent to the branded address.
3. Implement email authentication—Implementing a form of authentication for your branded email accounts can help protect your reputation and secure your mail delivery rates. B2C Service supports two forms of authentication.
   • Sender Policy Framework—Sender Policy Framework (SPF) is an email authentication option that designates permitted senders of email originating from your domain, excluding those with mismatched or incorrectly specified SPF records. See Answer ID 2489 on our support site for information about implementing SPF on your site.
   • DomainKeys/DomainKeys Identified Mail—DomainKeys (DK) and DomainKeys Identified Mail (DKIM) are email authentication options that use cryptographic signatures to designate email as originating from an authorized email delivery provider, excluding messages sent from those with unsigned or incorrectly assigned signatures. See Answer ID 2701 on our support site for information about implementing DK and DKIM on your site.
