Email Deliverability & SORBS Closure

What is SORBS and why was its closure significant for email marketers?

SORBS (Spam and Open Relay Blocking System) was a domain name system-based blackhole list (DNSBL) used to block spam and malicious emails from over 12 million host servers. Its closure on June 5, 2024, marked the end of a free, standalone service that had operated for more than two decades. While SORBS was praised for its transparency and ease of integration, its sudden decommissioning has prompted marketers to review their spam filtering strategies. Source: 4Thought Marketing Article

Does the closure of SORBS impact email deliverability for most marketers?

No, the closure of SORBS is unlikely to impact most marketers. SORBS was mainly used by hobbyist email administrators in recent years and was not particularly relevant in mainstream email marketing. However, those who relied on SORBS for spam filtering should consider alternative blocklists. Source: 4Thought Marketing Article

What alternatives to SORBS are available for spam filtering?

Marketers can use blocklists such as Spamhaus, SpamCop, Barracuda, and the Composite Blocking List (CBL). Newer players like Data443 (with Cyren) have also entered the market. These alternatives offer robust spam filtering capabilities. Source: 4Thought Marketing Article

What were the main criticisms of SORBS?

SORBS was criticized for being highly sensitive, overblocking IP ranges, and having issues accessing its databases. Some experts noted that it was less relevant for mainstream email marketing in its later years. Source: 4Thought Marketing Article

Will SORBS be reinstated or replaced?

There is hope within the community that SORBS will be taken over by legitimate sources rather than spammers, but as of now, the service remains decommissioned. Source: The Register

Email Deliverability Best Practices

What are the best practices for ensuring email deliverability?

Best practices include monitoring your IP reputation, analyzing spam scores, implementing authentication protocols (SPF, DKIM, DMARC), maintaining consistent sending volumes, keeping email lists clean, and sending high-quality content.

SORBS Closure: Does It Impact Email Deliverability?
By 4Thought Marketing

SORBS closure

The Spam and Open Relay Blocking System (SORBS), one of the oldest domain name system-based blackhole lists (DNSBLs), closed shop on June 5, 2024, after more than two decades online. The blocklist was acquired by Proofpoint Inc., in 2011 but continued operations as a free, standalone service until it was retired.

SORBS’ sudden closure with no real explanation other than the statement, “Please note that this service has been decommissioned and will no longer contain reputation data,” has ignited more than a few conversations about the future of free and open-source software and what the future may hold for the currently decommissioned SORBS. On a more practical level for email marketers, it’s a good reminder to monitor and improve your email deliverability.

SORBS: A History of Plaudits & Criticisms

In its heyday, SORBS allowed users to effectively block spam and malicious emails from more than 12 million host servers and counted several government organizations among its 200,000 patrons.

Widely regarded as a pioneer in the anti-spam industry, SORBS was praised by mail administrators for its ease of integration into mail server workflows as well as the ability to choose and reference blacklists at varying levels of strictness. It was SORBS’ transparent operating practices that won it the most praise.

Conversely, it faced criticism for being highly sensitive, overblocking IP ranges, and having issues accessing its databases. According to email anti-abuse expert Mickey Chandler, SORBS wasn’t particularly relevant in the email marketing industry and was mainly the domain of “hobbyist email administrators” in the years leading up to its closure. 

Will it be reinstated? The community hopes that SORBS will be taken over by legitimate sources instead of spammers who have expressed interest in acquiring the blocklist for years.

What Does This Mean for Email Marketing?

The closure of SORBS shouldn’t have an impact on most marketers. However, those who relied on SORBS for spam filtering will need to explore alternative blocklists. Spamhaus, SpamCop, Barracuda, and the Composite Blocking List (CBL) are a few that are already in existence while newer players like Data443, with Cyren, have been quick to jump onto the bandwagon.

The closure of SORBS is characteristic of the shift from open-source software to enterprise technology that leverages AI to recognize abnormal behavior patterns.

How Should Marketers Ensure Email Deliverability?

The answer is simple. It is to continue implementing the best practices for, and optimizing email campaigns. Some of them include:

  • Monitoring your IP: Monitoring your IP reputation remains a crucial step to avoid blacklisting. It is vital that your sender score is checked, and emails comply with any applicable regulatory requirements and privacy laws.
  • Analyze spam scores: Conduct email preview tests to assess your spam scores and take corrective actions where necessary.
  • Implement authentication protocols: Configure your domain with your own SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance to maintain control over your sender reputation. A fixed, static IP address can also help build reputation.
  • Consistent sending volumes are key: Spam filters monitor inconsistent behaviors, such as sudden spikes in email sending. Keeping your outgoing emails at consistent levels will help you avoid triggering these filters.
  • Maintain clean email lists: Old, outdated email addresses on your emailing lists can wreck your deliverability, resulting in higher bounce rates and raising red flags with spam filters.
  • High-quality content: What you send your subscribers matters. Creating high value content is a key factor in driving engagement and reaching your campaign goals.

Avoid Spam Filters by Maintaining Email Marketing Hygiene

Email marketing is an effective marketing strategy that offers robust ROIs. Integrated email marketing strategies can help maximize the impact of your email marketing campaign. Checking your sender reputation, analyzing your spam scores, effectively segmenting your subscriber list, adopting best practices, and addressing issues immediately are all ways you can keep your deliverability metrics on track.
