Recommended DMARC Record for Pulse

If you haven't set up a DMARC Record yet, please add the following TXT DNS Record. If one already exists, consider modifying your current record accordingly.

Type: TXT

Host/Name: _DMARC

Value: v=DMARC1;p=quarantine;sp=none;adkim=r;aspf=r;pct=100;fo=0;rf=afrf;ri=86400

Why You Should Have a DMARC Record

In response to Google, Yahoo, and other email providers implementing new regulations to combat SPAM, setting up a DMARC Record for your email domain is crucial. Considering this, we suggest specific settings for the DMARC Record to maximize email deliverability via Pulse.

When you verify your domain with Pulse, you are adding your DNS Records to a subdomain. This is the automated email you get when you first set up your Pulse account to Verify Your Domain. So it's important to configure your DMARC Record to recognize this setting; we'll explain this below.

What is a DMARC?

Domain-based Message Authentication Reporting & Conformance (DMARC) is a protocol designed to enhance email security. It accomplishes this by leveraging the Domain Name System (DNS), along with the DomainKeys Identified Mail (DKIM) and Sender Policy Framework (SPF) protocols, to authenticate the identity of email senders.

What are DMARC Policies?

The policy set by the domain owner in their DMARC record instructs the receiving email server on how to handle emails that fail DKIM and SPF verification yet claim to originate from the domain. This policy is indicated by 'p=' (main domain) and 'sp=' (subdomain) and offers three options:

None

Marked by 'p=none,' this directive instructs the receiving server to take no action upon receiving an email that doesn't meet the qualifications. Nevertheless, the server will dispatch email reports to the address specified in the DMARC record.

The 'sp=none' command signals to mail recipients that they should adopt a "none" policy for subdomains regardless of the policy set for the organizational domain.

Quarantine
Marked by 'p=quarantine,' this directive instructs the receiving server to quarantine any email that doesn't meet specified qualifications. As a result, emails will typically reach recipients’ spam folders.

The 'sp=quarantine' command signals to mail recipients that they should adopt a "quarantine" policy for subdomains regardless of the policy set for the organizational domain.

Reject
Marked by 'p=reject,' this directive instructs the recipient to block emails that don't meet the qualifications. It guarantees that only emails fully authenticated as originating from a domain are delivered to inboxes. Emails failing these verification checks will be rejected.

The 'sp=reject' command signals to mail recipients that they should adopt a "reject" policy for subdomains regardless of the policy set for the organizational domain.

Recommended DMARC Record for Pulse

If you haven't set up a DMARC Record yet, please add the following TXT DNS Record. If one already exists, consider modifying your current record accordingly.

Type: TXT

Host/Name: _DMARC

Value: v=DMARC1;p=quarantine;sp=none;adkim=r;aspf=r;pct=100;fo=0;rf=afrf;ri=86400

Given that your domain has been verified as a subdomain of Pulse, we advise implementing the 'sp=none' command to guarantee seamless delivery of all emails to your recipients. This strategy will significantly enhance your email deliverability.

If you would prefer to use a different 'sp=' command than 'sp=none,' then we recommend adding a separate DMARC Record for the Pulse subdomain:

Type:TXT

Host/Name: _dmarc.pulse.[domain].com

Value: v=DMARC1;p=quarantine;sp=none;adkim=r;aspf=r;pct=100;fo=0;rf=afrf;ri=86400

Adding a specific record for the subdomain will supersede the main domain's DMARC policy for that subdomain, as outlined above.
