Configure authoritative DNS records for Salesforce Marketing Cloud. Prevent spoofing, maintain high inbox placement at Google & Yahoo, and verify alignment without exceeding RFC 7208 lookup limits.

Required DNS Records for Salesforce Marketing Cloud

1. Sender Policy Framework (SPF)
Type: TXT
Host / Name:@
Value / Content:
v=spf1 include:cust-spf.exacttarget.com ~all
Uses 1 of your domain's 10 allowed DNS lookups under RFC 7208. Do not add duplicate SPF TXT records.
2. DomainKeys Identified Mail (DKIM)

Recommended DMARC Policy for Salesforce Marketing Cloud

Once both SPF and DKIM are verified on your domain, enforce DMARC to prevent attackers from sending unauthorized emails spoofing your brand:

v=DMARC1; p=reject; rua=mailto:dmarc-reports@yourcompany.com; pct=100; aspf=r; adkim=r
