Domain Deliverability Benchmarks for 2025
Cold email campaigns in 2025 achieve 98.16% delivery rates, but landing emails in inboxes remains a challenge. Key benchmarks like inbox placement rates (83.1% global average), bounce rates (<2%), and spam complaint rates (<0.1%) help measure success. Gmail leads with an 87.2% inbox placement rate, followed by Yahoo at 86%, while Outlook trails at 75.6%. Industries like real estate excel with 97.1% inbox rates, while telecom struggles due to stricter filtering.
To improve deliverability:
- Focus on authentication protocols (SPF, DKIM, DMARC).
- Maintain clean email lists to reduce bounces.
- Monitor engagement metrics like open and click rates.
- Use tools for automating DNS setup and compliance.
With AI-driven spam filters and stricter standards, consistent monitoring and infrastructure improvements are critical for success.
Key Metrics for Domain Deliverability
When it comes to cold email performance, key metrics play a crucial role in determining whether your emails land in inboxes or get blocked.
Inbox Placement Rate and Bounce Rate
The inbox placement rate measures the percentage of emails that successfully make it to recipients' inboxes. In 2025, the global average is 83.1%, but the best-performing domains can exceed 95%. For instance, the real estate industry leads with an impressive 97.1% inbox placement rate, thanks to its transactional email habits and highly engaged recipients.
On the other hand, the bounce rate tracks emails that fail to reach their destination. This can be broken into two categories:
- Hard bounces: These are permanent failures caused by issues like invalid email addresses, non-existent domains, or blocked senders. Hard bounces can immediately harm your sender reputation.
- Soft bounces: These are temporary failures, often due to full inboxes or server issues. While not as damaging as hard bounces, repeated soft bounces could point to deeper problems with your email list.
To maintain healthy deliverability, aim for a total bounce rate below 2%. These metrics lay the groundwork for evaluating both engagement and authentication.
Spam Complaints and Engagement Metrics
Keeping your spam complaint rate under 0.1% is critical for protecting your sender reputation.
For engagement metrics, strive for open rates between 15–25% and click-through rates of 2–5%, as these influence AI-driven email placement decisions.
An unsubscribe rate around 0.08% is considered standard. However, if you notice a sudden increase, it could indicate that your content isn't resonating with your audience or that your targeting is off.
"Procedures that usually took hours (setting DKIM, SPF, etc. records) for multiple domains, now take a few minutes."

Sender Reputation and Authentication
Your sender reputation is shaped by trends in complaints, bounces, and engagement. Email providers use this history to determine whether your emails are delivered, filtered, or blocked.
Authentication protocols like SPF, DKIM, and DMARC are essential for verifying your identity and preventing spoofing. For example, Microsoft now requires authentication for senders who deliver over 5,000 emails daily to consumer domains, effective May 2025. Tools like Mailforge simplify this process by automating the setup of DMARC, SPF, and DKIM, ensuring proper authentication in just minutes.
| Metric | 2025 Benchmark | Impact on Deliverability |
|---|---|---|
| Inbox Placement Rate | 83.1% (global average) | Indicates overall success |
| Bounce Rate | <2% | High rates harm reputation |
| Spam Complaint Rate | <0.1% | Essential for maintaining trust |
| Open Rate | 15–25% | Affects future email placement |
| Click-Through Rate | 2–5% | Reflects content relevance |
These metrics collectively provide a detailed picture of domain deliverability. Success depends on monitoring all these factors together. A domain with strong authentication, minimal complaints and bounces, and high engagement is well-positioned to achieve consistent deliverability.
2025 Deliverability Benchmarks by Major Email Providers
Knowing how your emails perform across various providers and industries is crucial for fine-tuning your campaigns. The latest data from 2025 highlights noticeable differences in deliverability rates, which can have a direct impact on your email marketing success. Below, we break down provider-specific metrics to help you make informed adjustments.
Deliverability Rates for Gmail, Outlook, and Yahoo
Gmail remains the leader in email deliverability, boasting an 87.2% inbox placement rate. This figure is well above the global average of 83.1%, solidifying Gmail as the go-to provider for reliable email delivery. Many businesses prioritize Gmail users due to this consistent performance.
Yahoo comes in close with an 86% inbox placement rate, showing a 6.96% improvement in Q2 2025 compared to Q1. This growth reflects Yahoo's ongoing efforts to refine its spam filters and improve sender reputation systems.
Outlook/Microsoft, while improving, lags behind at 75.6% inbox placement. Office365 users saw a 6.13% boost in Q2 2025, but Outlook’s higher spam filtering rate of 14.6% means marketers need to focus on authentication and list quality when targeting Microsoft domains.
Spam rates also reveal interesting trends: Gmail reports a 6.8% spam rate, Yahoo 4.8%, and Yahoo has a 9.2% undelivered email rate compared to Gmail’s 6%. These figures highlight the importance of tailoring your approach for each provider.
Industry-Specific Benchmarks
Deliverability rates vary significantly by industry, with some sectors outperforming others. Real Estate leads with inbox placement rates around 89%, thanks to highly engaged recipients and frequent transactional emails.

Factors Affecting Domain Deliverability in 2025
Email deliverability has become a far more intricate puzzle in 2025, as email providers now rely on advanced technologies and stricter standards. Three key factors stand out in determining whether your emails land in the inbox or are relegated to the spam folder.
AI-Powered Spam Filtering and Engagement-Based Algorithms
Email providers like Gmail and Outlook have taken spam filtering to the next level with machine learning algorithms that analyze sender behavior in real time. These systems don't just look for spammy keywords - they dig deeper into your sending habits and how recipients interact with your emails. As a result, engagement metrics now play a pivotal role in deliverability.
High engagement - measured through opens, clicks, and replies - can boost your chances of landing in the inbox. On the flip side, low engagement or high spam complaints (exceeding the industry standard of 0.1%) can quickly damage your sender reputation. AI filters are relentless; they can downgrade your reputation within hours if a single campaign performs poorly, and the effects can linger for weeks. This makes every email campaign critical.
In tandem with these advanced filters, solid authentication practices are now a non-negotiable part of maintaining good deliverability.
Authentication Standards and Compliance
By 2025, stringent authentication protocols have shifted from being a recommendation to an absolute requirement. Over 90% of top senders are now using robust authentication methods to ensure their emails are trusted by mailbox providers.
One standout development is BIMI (Brand Indicators for Message Identification), which allows verified logos to appear next to emails in supported inboxes. Though not universally adopted yet, businesses that implement BIMI report better engagement and trust from recipients.
Setting up authentication has also become easier, thanks to automated tools that can handle tasks like domain verification and DNS configuration in minutes instead of hours. But authentication alone isn’t enough. Compliance with regulations like CAN-SPAM in the U.S. and GDPR globally has become equally critical. These laws require clear sender identification, truthful subject lines, and functional unsubscribe links. Non-compliance doesn’t just risk legal trouble - it can also lead to deliverability penalties and long-term damage to your reputation.
With these stricter standards in place, businesses must also ensure their sending infrastructure and email lists are up to par.
Infrastructure and List Hygiene
Strong infrastructure and clean email lists are the backbone of successful email delivery. Features like automated DNS setup, SSL certificates, and domain masking are now standard for businesses managing large-scale email campaigns.
SSL certificates and domain masking not only protect your sender identity but also signal legitimacy to mailbox providers. These trust signals are becoming increasingly important as AI-powered filters grow more adept at spotting suspicious activity.
Meanwhile, list hygiene remains one of the most controllable factors for improving deliverability. Clean lists should keep bounce rates below 2% and aim for inbox placement rates of 95% or higher. Regularly cleaning and validating email lists has become a routine practice for top-performing senders.
Scaling these efforts is another challenge, especially for businesses with extensive outreach operations. Automated tools for bulk DNS updates and domain management have made it easier to maintain proper authentication across multiple domains. These tools are essential for ensuring consistent inbox placement at scale.
The numbers tell the story: in 2025, B2B email delivery rates averaged 98.16% when best practices were followed. However, senders with poor infrastructure and neglected email lists saw much lower performance. The gap between well-managed and poorly managed domains is widening as mailbox providers become more selective about what lands in the inbox.
Strategies for Benchmarking and Optimization
Transforming deliverability benchmarks into meaningful improvements takes a structured approach to measuring, monitoring, and refining your email practices. By 2025, the most successful businesses will combine industry insights with real-time monitoring tools and flexible infrastructure to maintain high inbox placement rates.
Using Benchmark Data for Performance Comparison
Benchmark data is a powerful tool for identifying weak points in your email strategy. Compare your performance to both industry standards and your historical metrics to uncover specific problem areas. For instance, if your overall inbox placement rate is 92%, but it dips to 75% for Microsoft Outlook users, you’ll know exactly where to focus your efforts.
Set achievable goals based on where you currently stand, rather than trying to hit industry benchmarks overnight. For example, if your bounce rate stands at 4.5%, aim to lower it by 0.5% each quarter. This gradual approach is more sustainable and allows for steady improvement over time. Regular performance reviews - weekly for immediate issues and monthly for long-term trends - can help you differentiate between temporary fluctuations and deeper problems that need action.
Tools and Techniques for Monitoring Deliverability
Once you’ve identified areas for improvement, continuous monitoring becomes essential. Tools like deliverability monitoring platforms and inbox placement testing services act as an early warning system, helping you spot issues before they escalate.
Automated alerts for sudden drops in metrics are invaluable. They let you intervene quickly, often preventing minor glitches from spiraling into major problems. Seed list testing, which checks inbox placement across various email providers, is another effective way to ensure your campaigns are landing where they should.
Authentication monitoring is equally critical. Regularly verify your SPF, DKIM, and DMARC records to avoid disruptions caused by DNS changes or server updates. Additionally, keep an eye on engagement metrics like open rates, click rates, and reply rates. These can serve as early indicators of deliverability issues, often before they show up in placement reports.
Role of Scalable Infrastructure Solutions
After setting goals and establishing monitoring systems, the next step is ensuring your infrastructure can support these optimizations. Scalable solutions like Mailforge are key for businesses aiming to maintain consistent inbox placement.
One common source of deliverability problems is misconfigured authentication records. Automated DNS setup can resolve this by ensuring uniform configurations across hundreds of domains from the start. Bulk DNS updates make it easy to keep up with changing provider requirements or evolving authentication standards, enabling you to update your entire domain portfolio at once and avoid compliance gaps.
For high-volume campaigns, cost efficiency is another major advantage. At just $3 per mailbox per month, Mailforge provides significant savings for businesses managing large-scale email operations.
Additional features like domain masking and SSL certificates enhance security and build trust - both of which are critical factors that spam filters consider when determining inbox placement. A distributed infrastructure approach spreads the sending load across multiple shared IP pools, reducing the pressure on individual domains and optimizing performance for cold outreach campaigns.
For businesses managing multiple brands or accounts, workspace organization features help keep domains and campaigns separate. This prevents sender reputation issues from spilling over between accounts while allowing for tailored optimization strategies. Plus, integration with existing sending platforms means you can enhance your infrastructure without disrupting your current campaign workflows.
| Infrastructure Feature | Deliverability Impact | Scalability Benefit |
|---|---|---|
| Automated DNS Setup | Reduces authentication errors | Ensures consistent setup for many domains |
| Bulk DNS Updates | Maintains compliance with changes | Streamlines updates across all domains |
| Domain Masking | Protects primary domain reputation | Manages risks and separates brand identities |
| Distributed IP Pools | Reduces sending pressure | Supports large campaigns without overloading |
