DMARC Analyzer - Improving Deliverability Using DMARC

This article contains information on improving email deliverability for bulk marketing emails by publishing a DMARC record, enhancing email authentication with SPF and DKIM, and gaining ISP trust to ensure messages reach recipients' primary inboxes.

Sending bulk marketing emails is a common and effective marketing approach. However, scaling up email marketing comes with deliverability problems. 

Email marketing allows organizations to reach large audiences at any one time. However this can also be risky as it leaves the organization vulnerable to attacks. It is still possible to get blacklisted by certain ISPs or that ISPs place messages in the recipient's spam folder.

By publishing a DMARC record for a domain, it lets ISP's (who have adopted DMARC) know that this domain wants to receive feedback about their email authentication. This enables an organization to receive feedback about the SPF and DKIM setup for this domain. With this information, an organization can improve their email authentication with SPF and DKIM.

Enabling a DMARC record also alerts ISPs that an organization is working on improving the security of their domain. ISPs want to ensure their customers receive legitimate messages and are not receiving any spam. ISPs are more likely to let messages pass from a domain that has published a DMARC record. Therefore, publishing a DMARC record in the domain (which is used for email marketing) can improve email deliverability. This ensures that messages that may have previously fallen into the recipient's spam folder are delivered directly into their primary inbox.
