Summary
The provided answers overwhelmingly suggest that a domain with a poor reputation *can* negatively affect other domains within the same Google Workspace. Experts, marketers, and documentation from various sources highlight that while Google isolates many factors, shared infrastructure (like IP addresses), similar sending patterns, content correlations, and Google's own data mining algorithms can all lead to reputation bleeding between domains. The degree of separation between businesses, the similarity of sending practices, and the management of shared resources influence the extent of the negative impact.
Key findings
- Reputation Interdependence: Domains within Google Workspace are not completely isolated and can influence each other's email deliverability.
- Algorithmic Correlation: Google's machine learning algorithms can identify relationships and correlate sending reputations based on various factors.
- Shared Infrastructure Risks: Shared IP addresses, resources, or content increase the risk of a negative reputation impact spreading.
- Sending Pattern Similarity: Similar sending practices across domains can lead to a correlated reputation, whether positive or negative.
- Google's Workspace Scrutiny: Google may scrutinize entire Workspaces for sending behavior, influencing deliverability across domains.
Key considerations
- IP Address Isolation: Consider using dedicated IP addresses for critical domains to isolate reputation issues.
- Separate Sending Practices: Ensure varied sending patterns across domains within the Workspace to prevent the algorithm from correlating them.
- Minimize Content Overlap: Avoid duplicating content across domains to reduce the chances of Google linking them negatively.
- Proactive Domain Management: Regularly monitor the reputation of all domains within your Google Workspace and quickly address any potential issues.
- Clear Business Separation: If possible, maintain a clear separation between the business functions of each domain and its sending practices to reduce the likelihood of negative association.
What email marketers say
11 marketer opinions
The consensus is that a domain with a poor reputation can negatively impact other domains within the same Google Workspace account. While each domain has its own reputation, the interconnected nature of Google Workspace allows for the spread of negative reputation, particularly if domains share sending patterns, content, or IP addresses. Google's algorithms can identify related domains and correlate their reputation scores. The degree of separation between domains, the similarity of sending practices, and the presence of shared resources all influence the extent of the impact.
Key opinions
- Reputation Interdependence: Domains within Google Workspace are not entirely isolated; the reputation of one domain can affect others.
- Algorithmic Correlation: Google's machine learning algorithms can identify relationships between domains and apply reputation scores accordingly.
- Shared Resources: Shared resources like IP addresses and similar content increase the risk of reputation spillover.
- Workspace Scrutiny: Google may scrutinize entire Workspaces if it detects poor sending habits from one or more domains.
- Proactive Separation: Separating critical functions onto domains with dedicated good reputations is advised.
Key considerations
- Sending Practices: Ensure all domains within the Workspace adhere to best practices for email sending to maintain a positive reputation.
- Domain Separation: Maintain clear separation between domains, especially for unrelated businesses, to minimize reputation bleed.
- Content Similarity: Avoid using similar content across multiple domains, as this can trigger Google's algorithms to link them.
- IP Address: If possible, ensure that domains with differing sending practices are not sharing IP Addresses as these can affect reputation.
- Workspace Management: Implement a comprehensive Workspace management strategy to monitor and mitigate any potential reputation issues.
Marketer view
Email marketer from Gmass explains that although domains are separate, interconnectedness exists within Workspace, meaning a damaged domain can reduce the deliverability of other domains on the same account.

What the experts say
3 expert opinions
Experts agree that a domain with a poor reputation can negatively affect other domains within the same Google Workspace. This is due to Google's ability to mine data and correlate related domains, especially when they share an IP address or exhibit similar sending patterns and content. Although the exact details of how Google connects these domains may not be readily accessible, the potential for reputation bleed is present.
Key opinions
- Data Mining: Google actively mines data and can potentially link domains within the same Google Workspace.
- IP Address Impact: Sharing an IP address between domains means a poor sending reputation on one can affect the deliverability of others.
- Correlation by Content/Patterns: Google's systems can correlate related domains based on similar sending patterns and content, influencing their reputations.
Key considerations
- IP Address Isolation: Consider using dedicated IP addresses for domains with critical sending reputations to prevent reputation bleed.
- Content and Sending Diversity: Ensure domains maintain distinct sending patterns and content to avoid Google linking them negatively.
- Reputation Monitoring: Regularly monitor the reputation of all domains within your Google Workspace to identify and address potential issues promptly.
Expert view
Expert from Email Geeks shares that he expects Google to mine any data they can get access to, but anyone outside Google probably doesn’t have easy access to the fact that the domains are related.

Expert from Word to the Wise (Laura Atkins) explains that related domains within the same organization (like those in a Google Workspace) can influence each other's reputation, particularly if they exhibit similar sending patterns or share content. Google's systems can correlate these domains.

What the documentation says
5 technical articles
Official documentation and technical resources indicate that a domain with a poor reputation can negatively affect other domains, especially within a shared environment like Google Workspace. While Google isolates many factors, domain-wide issues can affect deliverability, particularly if sending practices are similar or resources like IP addresses are shared. Although not specific to Google Workspace, these sources highlight the impact of shared resources and related sending profiles on domain reputation.
Key findings
- Workspace Impact: Google Workspace may experience deliverability issues across accounts due to a domain-wide reputation problem.
- Shared Resources: Shared resources (e.g., IP addresses) can lead to a reputation hit on one domain propagating to others.
- Similar Sending: Similar sending practices across domains within a Workspace can correlate their reputations.
- Co-located Impact: Co-located services or domains can be negatively impacted by a domain with a bad reputation.
- Reputation Correlation: Closely related domains with similar profiles may have correlated reputations.
Key considerations
- Sending Practices: Ensure varied sending patterns across domains within the Google Workspace to prevent the algorithm from correlating them.
- IP Addresses: Domains with differing sending profiles should use different IP Addresses
- Domain Monitoring: Monitor domain reputation and proactively resolve issues to maintain deliverability.
- Shared Infrastructure: Carefully manage domains with shared infrastructure, like an IP address, to prevent reputation bleed.
Technical article
Documentation from AWS explains that when domains share resources, such as an IP address, a sending reputation impacts all domains. Though not Google Workspace, this highlights the importance of domain management.

Technical article
Documentation from RFC explains that while RFC doesn't directly address Google Workspace, its outlining of email infrastructure indicates that if domains share resources or IPs, a reputation hit on one can propagate to others.
