How to Monitor Email Deliverability in Real Time
Monitoring email deliverability in real time ensures your emails reach the inbox, not the spam folder. Here’s why it matters and how to do it effectively:
- Real-Time Insights: Traditional metrics like open rates only show engagement after delivery. Real-time monitoring tracks inbox placement, spam rates, and bounce rates, giving you immediate feedback.
- Cold Email Challenges: Cold outreach faces stricter spam filters and higher bounce rates. Tools like Infraforge help manage IP reputation, authentication protocols (SPF, DKIM, DMARC), and feedback loops.
- Key Metrics: Focus on inbox placement rates (aim for 70%+), spam rates (<0.1%), and bounce rates (<2%). Authentication checks are critical for avoiding spam filters.
- Tools to Use: Platforms like Infraforge, GlockApps, and MailMonitor provide solutions for testing, monitoring, and improving deliverability.
Quick Tip: Combine dedicated IPs, domain authentication, and real-time alerts to quickly address issues and maintain a strong sender reputation.
Core Metrics and Signals for Email Deliverability
Understanding key deliverability metrics is essential for identifying issues and optimizing your email campaigns.
Inbox Placement and Spam Rates
Inbox placement rates reveal where your emails end up - whether they land in the primary inbox, get flagged as spam, or are sorted into promotional folders. This metric is crucial because it directly shows how many people actually see your message.
To measure inbox placement, seed testing is the go-to method. Tools like MailMonitor and GlockApps send test emails to monitored inboxes across major providers like Gmail, Outlook, and Yahoo. These tools then report the percentage of emails landing in each folder, giving you a clear picture of your deliverability performance.
Cold email campaigns often face stricter filtering, leading to lower placement rates. If your inbox placement rate falls below 70%, it’s a red flag that requires immediate action.
Spam rates are closely tied to inbox placement. When recipients mark your emails as spam - or when email providers automatically filter them - it affects your sender reputation. The standard here is strict: spam rates should stay below 0.1%. Even a slight increase can trigger penalties that impact future campaigns.
Todd B., President of a PR firm, used MailMonitor to analyze how different email clients and platforms responded to his outreach. By identifying emails that weren’t reaching inboxes, he resolved key issues and significantly improved his deliverability and campaign outcomes.
Next, examining bounce rates and authentication checks helps refine your overall strategy.
Bounce Rates and Authentication Checks
Bounce rates highlight delivery failures and come in two forms, each requiring a different approach. Hard bounces occur due to permanent issues, like invalid email addresses or blocked domains. Soft bounces happen when temporary problems, such as full inboxes or server downtime, prevent delivery.
Both types can harm your sender reputation, but hard bounces are particularly damaging. A hard bounce rate exceeding 2% can lead to spam filters or blacklisting by major ISPs . Monitoring tools can flag these events, allowing you to clean up invalid addresses and retry soft bounces before they escalate.
Authentication checks through SPF, DKIM, and DMARC protocols are essential for modern email delivery. These protocols verify that you’re authorized to send emails from your domain and protect against spoofing. Failing these checks often results in emails being sent to spam or rejected outright.
Real-time tools can test your SPF, DKIM, and DMARC setup and notify you of any failures. For instance, MailMonitor runs regular checks and alerts users to issues, helping maintain trust with ISPs. The goal? A 100% authentication pass rate to ensure reliable delivery.
| Metric | What It Measures | Why It Matters | Benchmarks |
|---|---|---|---|
| Hard Bounce Rate | % of emails permanently undeliverable | High rates can lead to blacklisting | <2% |
| Soft Bounce Rate | % of emails temporarily undeliverable | Indicates list or server issues | <2% |
| Authentication Pass | SPF/DKIM/DMARC status | Essential for inbox delivery | 100% pass recommended |
Reputation monitoring and engagement metrics further complete a well-rounded deliverability strategy.
Reputation Monitoring and Engagement Metrics
Your IP and domain reputation scores play a big role in how ISPs treat your emails before even looking at their content. These scores are based on your sending history, complaint rates, and overall trustworthiness. A strong reputation boosts inbox placement, while a poor one can lead to automatic filtering.
To stay ahead, automatic blacklist checks are a must. Tools like MailMonitor perform regular scans and send alerts if your IP or domain gets listed. This allows you to address issues quickly before they derail your campaigns.
Engagement metrics - like open rates, click-through rates, and reply rates - are another critical factor. ISPs use these metrics to gauge the quality of your emails. High engagement signals that recipients value your messages, which improves future deliverability. On the flip side, low engagement or high complaint rates can damage your reputation over time.
For cold email campaigns, benchmarks typically range from 15-28% open rates and 2-5% click rates, though these numbers can vary depending on your industry and approach. Monitoring trends is key - sudden drops in engagement often point to deliverability problems that need immediate attention.
Modern platforms aggregate these metrics, offering actionable insights to improve your campaigns. They can help you identify issues like spammy subject lines or failed authentication, enabling you to resolve problems quickly .
Infraforge takes this a step further with features like dedicated IPs, automated DNS setup, and pre-warmed domains, ensuring strong reputation management for large-scale cold email campaigns.

Step-by-Step Guide: Setting Up Real-Time Email Monitoring
Real-time monitoring is crucial for keeping your email campaigns on track. This guide walks you through the steps needed to set up effective deliverability tracking, ensuring you can spot and resolve issues quickly. Automating key technical setups means you can start monitoring your email performance in just minutes.
Initial Setup: Domain Authentication and Tool Integration
The first step is authenticating your domain. Tools like Infraforge simplify this process by automatically configuring SPF, DKIM, and DMARC records following industry standards. With Infraforge, your domain and DNS records (SPF, DKIM, DMARC) can be fully set up in about five minutes.
If you prefer a manual approach, you'll need to access your domain's DNS settings. This involves creating an SPF record to define which IP addresses are authorized to send emails on your behalf, generating DKIM keys, and adding the public key to your DNS records. While effective, manual setup requires a solid understanding of DNS management.
Infraforge also integrates smoothly with popular platforms like Salesforge, allowing you to continue using your existing tools while gaining access to advanced deliverability tracking.
Once your domain is authenticated, the next step is configuring real-time alerts to keep tabs on your email deliverability.
Configuring Monitoring and Alerts
Real-time alerts are essential for catching issues before they impact your campaigns. Infraforge’s dashboard offers real-time monitoring and customizable alerts for key issues like bounce rates, spam complaints, and authentication failures. For example, setting a spam complaint alert at a 0.1% threshold can help you address problems early, reducing the risk of being blocked by ISPs.
If you’re using Amazon SES, you can take advantage of Amazon SNS for detailed bounce and complaint tracking. Start by creating an SNS topic and configure Amazon SES to send notifications to it. Update your SES verified identity settings to route feedback notifications - such as bounce and complaint messages - through your SNS topic. You can also set up an event destination in your configuration to monitor "hard bounces" and "complaints", giving you more control over which campaigns trigger alerts.
To avoid being overwhelmed by alerts, consider setting escalation rules. This way, persistent issues trigger higher-priority notifications, ensuring that critical problems are addressed promptly.
With real-time alerts in place, you can focus on optimizing your campaigns based on the insights you gather.
Optimizing Campaigns Based on Insights
If you notice spam complaint rates exceeding 0.1%, it’s time to review your email content for potential spam triggers. Poor deliverability can slash email revenue by as much as 30%, so quick action is essential.
Use the insights from your monitoring tools to maintain a clean email list. Remove hard bounces immediately and implement a sunset policy to phase out inactive subscribers, protecting your sender reputation. Additionally, analyzing engagement patterns can reveal which types of content resonate most with your audience, helping you refine your approach.
Consistency in sending volumes is another key to better deliverability. Sending large, irregular batches of emails can hurt your reputation. As email deliverability expert Tony Patti advises:
"Don't send 50,000 emails on Monday, take two weeks off, and then send five million".
Leverage your monitoring data to identify the best sending volumes and timings for your campaigns.
Lastly, track your performance by aiming for a marketing email deliverability rate of 85% or higher, with 90%+ considered ideal. For transactional emails, strive for a deliverability rate of 95% or above, ideally nearing 98.99%. Monitoring these metrics consistently over time - not just for individual campaigns - will help you achieve sustained improvements in email performance.

Advanced Strategies for Deliverability Optimization
When managing large-scale email campaigns, advanced strategies are essential to maintain high deliverability rates. These techniques go beyond basic monitoring, actively enhancing email performance and ensuring your messages reach their intended recipients.
Multi-IP Provisioning and Domain Masking
To safeguard sender reputation and improve deliverability, distributing email volume across multiple dedicated IPs is a game-changer. This approach, known as multi-IP provisioning, isolates campaigns, ensuring that issues with one IP don’t affect others. For example, you can dedicate one IP to transactional emails and another to outreach campaigns. If one encounters deliverability problems, the rest of your campaigns remain unaffected.
Infraforge offers a multi-IP provisioning service at $99 per IP per month, making it easier to implement this strategy at scale.
Domain masking adds another layer of protection. By redirecting emails through masked domains, you shield your primary domain from potential reputation damage while maintaining a professional appearance. Infraforge provides SSL and domain masking services for just $2 per domain per month, ensuring secure redirections that protect your brand.
When combined, multi-IP provisioning and domain masking create a robust setup, especially valuable for businesses scaling from hundreds to thousands of emails daily. This ensures your sender reputation remains intact, even as your email volume grows.
Automated Warm-Up Routines and Real-Time Analytics
A strong infrastructure is just the beginning - implementing effective warm-up routines is critical for improving inbox placement rates. Warm-up routines gradually build trust with Internet Service Providers (ISPs), significantly boosting deliverability. Warmed-up email accounts can achieve inbox placement rates of up to 98%, compared to just 75% for non-warmed-up domains.
Start small, sending 10–20 emails daily, and increase the volume by 10–20% each week. Over time, this controlled approach can lead to a 30% improvement in inbox placement rates. Studies reveal that businesses using warm-up strategies see open rates climb by as much as 30% within the first month.
Infraforge simplifies this process with automated domain warm-up tools. These tools ensure gradual, consistent activity that aligns with ISP expectations, saving you time while preparing your email infrastructure for large-scale use.
Real-time analytics further enhance this process. By closely monitoring metrics like open rates (aim for over 20%) and bounce rates (keep them below 2%), you can adjust your sending patterns as needed. Immediate adjustments based on real-time data prevent small issues from escalating into major problems.
Nearly 50% of marketers report improved deliverability after adopting automated warm-up tools. The key is consistency - avoid sudden spikes in email volume, which can trigger spam filters and harm your sender reputation.
Centralized Monitoring for Large Campaigns
Once individual components are optimized, centralized monitoring ties everything together, offering a comprehensive view of your campaigns. This approach is particularly useful for managing large-scale outreach efforts or multiple client accounts.
Infraforge’s Masterbox feature, priced at $7 per workspace per month, provides a unified dashboard for real-time monitoring. Instead of juggling multiple dashboards, you can track bounce rates, engagement metrics, and deliverability issues all in one place.
With centralized monitoring, you can identify and address problems immediately. For instance, if a campaign shows elevated bounce rates or spam complaints, you can pause it before it negatively impacts other campaigns. This proactive approach is crucial when sending high volumes of emails - waiting for daily reports could mean thousands of emails have already been affected.
Additionally, centralized monitoring helps you spot performance trends across campaigns. For example, you might notice that certain subject lines or specific sending times consistently perform better. Armed with this data, you can refine your overall outreach strategy, ensuring better results across the board.
For agencies or businesses managing multiple brands, centralized monitoring ensures consistent deliverability standards while allowing for tailored adjustments to individual campaigns. This balance of oversight and flexibility is critical for maintaining high performance across all accounts.
