How to configure SFMC to send on behalf of sales reps with DKIM/DMARC authentication?

Configuring SFMC for sending on behalf of sales representatives with DKIM/DMARC authentication is achievable and doesn't cause conflicts with other systems. It necessitates both a Sender Authentication Package (SAP) and a Private Domain for top-level domain sending, with SAP handling link/image wrapping. Utilize subdomains for the SAP (e.g., email.domain.com) to ensure DMARC alignment. SPF checks in SFMC occur at the bounce domain level, emphasizing proper DKIM setup. Subdomain usage isolates email reputation, and avoiding top-level domain reply-to addresses when using subdomains prevents address book issues. Crucial steps also include generating DKIM key pairs, publishing the public key in DNS, configuring SFMC with the private key, configuring Reply Mail Management (RMM) to process replies and unsubscribes, monitoring and improving sender reputation, and correctly setting up DMARC records to prevent domain spoofing. Using inbox placement tests, measure the impact of SPF, DKIM and DMARC records.

To configure SFMC for sending on behalf of sales representatives with proper DKIM/DMARC authentication, it's essential to ensure SPF and DKIM are correctly set up. SPF authorizes sending sources, while DKIM signs emails. Using a subdomain isolates email reputation and allows individual DKIM settings. Consistently monitor and improve sender reputation, using SPF, DKIM and DMARC. Regularly checking your IP and domain reputation, addressing spam complaints, and maintaining sending volumes are crucial. Correctly setting up DMARC records instructs receiving servers on handling unauthenticated messages, preventing domain spoofing. Finally, employ inbox placement tests to evaluate the impact of SPF, DKIM, and DMARC records on deliverability.

Configuring SFMC to send on behalf of sales representatives with DKIM/DMARC authentication involves several key steps and considerations. It's feasible and won't create conflicts; DKIM can exist in multiple places. Implementing both a Sender Authentication Package (SAP) and a Private Domain is crucial for sending as a top-level domain, with SAP handling link/image wrapping and the Private Domain enabling the use of the top-level domain in the 'From' address. When using subdomains for sending (e.g., e.domain.com), avoid reply-to addresses at the top-level domain to prevent address book issues. Best practice involves using a subdomain for the SAP (e.g., email.domain.com) to ensure proper DMARC alignment with the top-level domain in the 'From' address. In SFMC, SPF checks occur at the bounce.email.domain.com level, so the top-level domain SPF isn't necessary, relying instead on correct DKIM setup. Ensure that SPF, DKIM and DMARC are correctly setup.

Configuring SFMC to send on behalf of sales reps with DKIM/DMARC authentication, per Salesforce documentation, requires implementing a Sender Authentication Package (SAP) for authentication, including a dedicated IP, branded domain, and DKIM signing. DKIM setup involves generating a key pair, publishing the public key in DNS, and configuring SFMC with the private key. Proper configuration of SPF syntax is also essential. To handle replies effectively, configure Reply Mail Management (RMM) to route replies to the correct sales rep and process out-of-office and unsubscribe requests. DKIM specifications are outlined in RFC documentation, detailing digital signatures for email integrity.
