How does Gmail's compliance status dashboard aggregate spam rate data for root domains and subdomains?

Email marketer from GMass explains how warming up subdomains helps build a positive sending reputation over time, improving deliverability rates and preventing emails from landing in the spam folder.

Email marketer from Neil Patel Digital shares that using subdomains can help isolate deliverability issues. If one subdomain has a poor sending reputation, it won't necessarily impact the reputation of the root domain or other subdomains.

Email marketer from Litmus explains that using a dedicated subdomain for marketing emails helps protect your primary domain's reputation, ensuring important transactional emails are delivered reliably.

Email marketer from Validity (formerly Return Path) shares insights on how mailbox providers evaluate sender reputation based on various factors, including spam complaints, engagement metrics, and authentication practices, across both root domains and subdomains.

Email marketer from Reddit shares that while subdomains can have their own reputation, they are still somewhat linked to the root domain. If the root domain is blacklisted, it can impact the subdomain's deliverability as well.

Email marketer from Mailjet shares strategies of using subdomains for different types of emails (transactional, marketing) can help segment sending reputation and protect the primary domain's reputation.

Marketer from Email Geeks shares information regarding the compliance status dashboard, explaining it shows results aggregated to the root domain, not subdomains. This raises the possibility that the "/v2/" dashboard with spam rates may also be showing data for the primary domain, not the subdomain, as per Google's documentation.

Email marketer from Stackoverflow mentions that Google Postmaster Tools provides separate dashboards for the root domain and subdomains, allowing you to monitor spam rates and reputation for each individually.

Email marketer from Sendgrid answers that using dedicated IP addresses for different subdomains allows for more granular control over sending reputation, as each subdomain's sending practices won't directly affect others.

Marketer from Email Geeks explains that for v1, subdomain data rolls up to the root domain, and subdomain sending data is visible both at the subdomain level and root domain level in GPT (presumably Google Postmaster Tools).

Email marketer from Email on Acid shares the importance of monitoring email deliverability across both root domains and subdomains to identify and address any potential issues early on, preventing long-term damage to sender reputation.

Expert from Word to the Wise, Laura Atkins, explains that proper domain setup including authentication, and monitoring of sending reputation for both the root domain and any subdomains is critical for maintain deliverability. She also mentions that some providers may treat subdomains differently, so it's essential to understand the specific policies of each provider.

Expert from Spam Resource, John Levine, explains that using subdomains can be a good strategy for separating different types of email traffic (e.g., marketing vs. transactional) and isolating reputation issues. However, it's crucial to properly configure authentication (SPF, DKIM, DMARC) for each subdomain.

Documentation from DMARC.org specifies that Domain-based Message Authentication, Reporting & Conformance (DMARC) policies can be applied to both root domains and subdomains, allowing for granular control over email authentication enforcement.

Documentation from Google Workspace Admin Help explains that the Compliance status dashboard data applies to primary domains only, not to subdomains. This means spam rate data displayed in the dashboard is aggregated at the root domain level.

Documentation from RFC Editor (RFC 4408) specifies how Sender Policy Framework (SPF) records work with subdomains. Each subdomain needs its own SPF record to properly authenticate email sending from that subdomain.

Documentation from DKIM.org explains that DomainKeys Identified Mail (DKIM) signatures can be configured independently for each subdomain, allowing for specific authentication keys and policies for different sending sources.

Documentation from Postmark explains that domain reputation is crucial for email deliverability. While subdomains can have independent reputations, a severely damaged root domain reputation can negatively impact all subdomains.
