Summary
When a G Suite IP is blacklisted on SORBS, a multifaceted approach is needed. As G Suite uses shared IPs, the actions of other users can impact your deliverability. Initial steps involve understanding the reason for the listing (dynamic IP, spam trap, etc.) and checking other DNSBLs. Experts recommend improving your sending reputation through email authentication (SPF, DKIM, DMARC), list hygiene (removing invalid addresses, avoiding spam traps), and following bulk sender guidelines. Use monitoring tools to track your domain's reputation and deliverability testing to identify issues. While SORBS might not be the direct cause, it could indicate a larger problem. Contact SORBS directly for removal requests after addressing underlying issues, and note some blocks may be permanent. Ensuring G Suite is in your SPF record is vital for dynamic IPs.
Key findings
- Shared IP Implications: G Suite's shared IP environment means other users' actions affect your IP's reputation.
- Multiple Causes: Blacklisting can stem from various reasons, including dynamic IPs, spam traps, or other policy violations.
- Reputation Matters: A strong sender reputation is key, built on authentication, clean lists, and responsible sending practices.
- Monitoring is Essential: Continuous monitoring helps identify and address issues quickly, including potential blacklist entries.
Key considerations
- Diagnose the Cause: Understanding the specific reason for the SORBS listing is essential for effective remediation.
- Assess the Impact: Evaluate the real impact of the SORBS listing, as other factors might be contributing to deliverability issues.
- Follow Guidelines: Adhere to Google's bulk sender guidelines to maintain a positive sending reputation within the G Suite environment.
- Contact SORBS: If warranted, contact SORBS directly after addressing underlying issues to request removal.
- SPF Validation: Ensure your SPF record properly authorizes G Suite to send emails on your behalf, especially with dynamic IPs.
What email marketers say
13 marketer opinions
When a G Suite IP is blacklisted on SORBS, the core issue stems from the use of shared IP addresses, meaning the actions of other users can impact your email deliverability. Experts recommend a multi-faceted approach to address this. This involves checking if the IP is shared, understanding the reason for the listing, and requesting delisting if appropriate. Improving your sending reputation is vital through email authentication (SPF, DKIM, DMARC), list hygiene (cleaning inactive emails, avoiding spam traps, double opt-ins), and consistent monitoring of your domain's reputation. Additionally, investigate if the SORBS listing is the true cause, as it may indicate a broader deliverability problem requiring a more holistic solution. Utilizing deliverability testing tools and warming IP addresses can also contribute to better email placement.
Key opinions
- Shared IPs: G Suite utilizes shared IPs, where the sending behavior of multiple users impacts overall IP reputation.
- Holistic Issues: A SORBS listing might be a symptom of a larger email deliverability problem rather than the direct cause.
- Proactive Measures: Improving sending reputation through authentication, list hygiene, and monitoring is crucial.
- Tools and Testing: Deliverability testing tools and IP warming strategies can aid in email placement and reputation management.
Key considerations
- Reason for Listing: Determine the specific reason for the SORBS listing to address the underlying problem effectively.
- SORBS Impact: Assess the actual impact of the SORBS listing on email delivery, as it may not be the primary cause of deliverability issues.
- Contact Google: Contacting Google for support might be necessary, especially if the issue persists despite your efforts.
- Ongoing Monitoring: Implement continuous monitoring of your domain's reputation and blacklist status to identify and resolve any issues promptly.

What the experts say
2 expert opinions
Experts advise understanding the reason for the SORBS blacklist inclusion as the first step. Determine if it's due to a dynamic IP, spam trap, or general spam listing. Some blocks are temporary and will expire, while others are permanent and unremovable if the underlying cause is too severe. If the block is due to a dynamic IP, ensure G Suite is authorized in your SPF record. Remove yourself from the list if possible, and then continuously monitor the situation.
Key opinions
- Diagnostic Importance: Understanding the type of listing (dynamic IP, spam trap, etc.) is critical for appropriate action.
- Block Permanence: Some blacklist entries are permanent based on the severity of the violation.
- SPF Record: Proper configuration of SPF records is essential to authorize G Suite as a valid sending source.
Key considerations
- Cause Identification: Thoroughly investigate the root cause of the blacklisting before attempting removal.
- Removal Possibility: Assess whether removal is even possible based on the blacklist's policies and the severity of the infraction.
- Continuous Monitoring: Implement ongoing monitoring to detect future issues and ensure successful removal.
Expert view
Expert from Spam Resource recommends diagnosing the reason for the block. Sometimes a block is permanent and cannot be removed if the cause of the block is too risky to the reputation of the blacklist. Often the block is temporary so wait for the block to expire.

Expert view
Expert from Word to the Wise explains that you need to understand why you're on the SORBS list. Determine if it is a dynamic IP listing (dial-up or residential IP), a spam trap listing or a general spam listing. Residential IPs can be harder to remove, so make sure GSuite is allowed in your SPF record to show it's a valid source. Remove yourself from the list and then monitor.
