Summary
When your domain reputation with Gmail is healthy, but email click rates are declining, it can be perplexing, especially if Google Postmaster Tools shows your shared IP reputation as only "Fair". While it's tempting to blame the shared IP address, Gmail often prioritizes domain reputation and user engagement over the specific IP's standing, particularly if emails are still reaching the inbox. This scenario often points to underlying issues with list quality, audience engagement, or content relevance, rather than a direct deliverability block. Understanding the interplay between these factors is key to effective troubleshooting.
Key findings
- Domain vs. IP reputation: Gmail primarily weighs domain reputation more heavily than IP reputation for inbox placement, even if bounce messages or Google Postmaster Tools might suggest otherwise.
- Fair IP score: A "Fair" IP reputation in Google Postmaster Tools may not necessarily indicate a deliverability problem if your emails are consistently landing in the inbox. It could just be an informational data point.
- Declining clicks: A drop in click-through rates, despite a healthy domain and authentication status, frequently suggests issues with list hygiene, audience aging, or content relevance rather than a direct email deliverability block due to IP.
- ESP limitations: Some ESPs (Email Service Providers) might decline to move clients to different shared IP pools based on internal policy, making direct intervention on the IP side challenging.
Key considerations
- Comprehensive analysis: Always evaluate your deliverability using a holistic approach. Check if your mail is actually going to the spam folder, for instance, via seed testing or feedback from personal Gmail accounts. If it's inboxing, the IP reputation might not be the cause of declining clicks.
- List quality: Investigate whether your audience is aging or if your list quality has degraded over time, as this directly impacts engagement. Consider performing a thorough audit of your subscriber engagement.
- Authentication: Ensure your DKIM and SPF authentication protocols are properly configured and aligned with your sending domain, not just the ESP's domain.
- Direct contact with Gmail: While you can submit a ticket to Gmail via their Sender Contact Form, the likelihood of a resolution specifically for shared IP issues impacting clicks is generally low.
- ESPs and dedicated IPs: If a shared IP issue is definitively impacting deliverability, consider escalating with your ESP to be moved to a different shared IP pool or, if feasible, explore the option of a dedicated IP address.
What email marketers say
Email marketers frequently face the challenge of declining engagement metrics. Many report that while shared IP reputation might seem like the obvious culprit, particularly when observed as 'Fair' in Google Postmaster Tools, the reality often lies in factors such as audience quality and overall email strategy. They emphasize the importance of deep-diving into engagement data and avoiding a sole focus on IP status if emails are still reaching the inbox.
Key opinions
- Domain preference: Many marketers find that Gmail's algorithms prioritize domain reputation above IP reputation, meaning a strong domain can often mitigate the impact of a less-than-perfect shared IP.
- Engagement metrics: Declining open and click rates are frequently attributed to issues with audience aging or changes in subscriber engagement patterns, rather than strictly deliverability problems.
- Inbox placement first: If emails are consistently hitting the inbox, marketers suggest that a 'Fair' IP reputation in Postmaster Tools is likely not the cause of reduced clicks. The problem then shifts to post-inbox engagement.
- List quality: Issues such as a degrading list quality over time, especially due to a lack of new, engaged subscribers, can significantly impact overall campaign performance and click rates.
Key considerations
- Deep dive into data: Marketers recommend a thorough investigation of all available data points, including conversion rates and seed testing results to Gmail, to confirm actual inbox placement before concluding on IP impact.
- Audience segmentation: Even with consistent segmentation, the activity levels within those segments can shift. Marketers suggest analyzing audience cohorts to identify if specific groups are becoming less engaged, which directly impacts click rates.
- ESP negotiation: If evidence points to a genuine shared IP issue, marketers advise pushing your ESP for a move to a different, cleaner pool of shared IPs or considering a dedicated IP address.
- Holistic deliverability: Marketers frequently suggest that a drop in engagement might be symptomatic of broader deliverability challenges, highlighting the importance of understanding why emails go to spam if not due to IP reputation. This includes looking at content, frequency, and subscriber feedback. Additional advice can be found in this guide on IP reputation.
Marketer view
Marketer from Email Geeks states their IP reputation turned to "Fair" and clicks started to drop, leading them to assume it's a deliverability issue given consistent domain reputation and segmentation.
Marketer view
Marketer from Mailmodo suggests that using a shared IP address without proper management can negatively affect IP reputation, leading to deliverability issues.
What the experts say
Experts in email deliverability consistently highlight that while IP reputation plays a role, Gmail's sophisticated algorithms give significant weight to domain reputation and actual user engagement. They often advise against immediately blaming a shared IP's 'Fair' status for declining clicks if direct inboxing is still occurring, pointing instead to deeper audience and content issues.
Key opinions
- Domain precedence: Experts agree that Gmail places a higher priority on domain-level reputation for deliverability outcomes, often viewing IP reputation as a secondary factor.
- Not a problem: If emails are still reaching the inbox, a 'Fair' shared IP reputation in Google Postmaster Tools is frequently considered an interesting data point, not necessarily a deliverability problem requiring immediate action.
- Audience aging: Gradual declines in engagement (like click rates) are often symptoms of an aging audience or a weakening acquisition funnel, rather than a sudden deliverability block.
- Limited support: Directly opening tickets with Gmail regarding shared IP reputation issues typically yields low chances of a custom resolution, as their systems are designed to manage shared environments automatically.
Key considerations
- Authentication check: Verify that your DKIM and SPF records are correctly configured and align with your primary sending domain to reinforce trust with Gmail.
- Google Postmaster Tools: Regularly monitor your domain reputation within Google Postmaster Tools. This resource provides crucial insights into how Gmail perceives your sending practices, impacting not only IP reputation but overall deliverability with stable open rates.
- Cohort analysis: To identify audience aging, experts recommend utilizing cohort graphs (or similar analyses) to track user engagement from their signup date, revealing if older segments are losing interest over time. This guidance is also discussed by Evaboot in their blog about sender reputation.
- Pushing ESPs: If internal data (like seed testing to spam) strongly suggests a shared IP issue, experts advise escalating the request with your ESP to be moved to a different shared IP pool or to a dedicated IP.

What the documentation says
Official documentation from major email providers like Google emphasizes the paramount importance of sender reputation. While IP reputation is mentioned, the focus is largely on domain trust, authentication, and user engagement metrics as key determinants of deliverability. They outline best practices that senders should follow to ensure their emails reach the inbox, even within shared IP environments.
Key findings
- Sender reputation pillars: Documentation from Google Postmaster Tools highlights domain reputation, authentication (SPF, DKIM, DMARC), and user engagement (opens, clicks, spam complaints) as the primary factors influencing inbox placement.
- Shared IP handling: Google's systems are designed to differentiate between good and bad senders on shared IP addresses, meaning a 'Fair' IP reputation for the shared pool might not automatically penalize a sender with a strong domain reputation.
- Engagement signals: Low engagement rates, high complaint rates, and significant bounce rates are recognized as strong negative signals that can independently impact deliverability, regardless of the IP status.
- Monitoring tools: Google Postmaster Tools is the recommended resource for senders to monitor their deliverability performance to Gmail, providing metrics on IP reputation, domain reputation, spam rates, and feedback loops.
Key considerations
- Adhere to guidelines: Comply with Google's bulk sender guidelines, which primarily focus on sending solicited mail, managing recipient expectations, and providing easy unsubscribe options. Read our ultimate guide to Google Postmaster Tools.
- Robust authentication: Prioritize proper setup and maintenance of SPF, DKIM, and DMARC records to establish sender authenticity and protect your domain reputation. Our list of DMARC tags can help you understand your policy.
- Monitor engagement: Actively monitor recipient engagement and promptly remove unengaged subscribers to prevent negative feedback that could impact both IP and domain reputation.
- Blacklist monitoring: While not directly caused by fair shared IP, documentation generally suggests that frequent listing on blacklists (or blocklists) indicates severe sending issues that require immediate attention. Learn more about improving sender reputation with email hygiene.
