How to Check and Improve Your Email Sender Reputation for 2025
Discover how to boost your email sender reputation and improve deliverability. Learn about IP and domain reputation, key factors affecting sender scores, and tools to monitor your standing. Implement best practices to ensure your emails reach inboxes consistently.
A staggering one-sixth of all emails never make it to the inbox. The numbers tell a concerning story - 17% of emails land in spam folders or vanish into the digital world.
Many marketers face this frustrating reality. They spend countless hours perfecting email campaigns that fail to reach their target audience because of poor email sender reputation.
Your email sender reputation works similar to a credit score for email marketing activities. Internet Service Providers (ISPs) evaluate this score to determine if your emails deserve inbox placement or relegation to spam folders.
The situation isn't hopeless. You can understand, monitor and enhance your email sender reputation effectively. This piece outlines proven strategies that will boost your deliverability rates. Your messages will consistently reach their rightful destination - your subscribers' inboxes.
Want to master email deliverability? Let's take a closer look at how you can make it happen!
What Is Email Sender Reputation?
Email sender reputation works just like your digital credit score in email marketing. ISPs use this complete measure to decide if your emails belong in the recipient's inbox or should be filtered as spam.
Let's look at the two elements that build your sender reputation:
IP Reputation
Your IP reputation connects directly to the IP address you use to send emails. This works like your email sending address's track record. When you send emails through an Email Service Provider (ESP), you'll either use a shared IP that multiple senders use or a dedicated IP that belongs to just one sender.
Key factors affecting IP reputation include:
- Sending volume and consistency
- Bounce rates and complaints
- Spam trap hits
- Historical sending patterns
Domain Reputation
Domain reputation measures your sending domain's credibility - your brand's email identity. Domain reputation is vital because it stays with you even if you switch your IP address or email service provider.
Domain reputation becomes significant because ISPs assess it everywhere your domain shows up in an email, including:
- From Address
- Return-Path Domain
- DKIM Signing Domain
- Links and headers
The sort of thing I love about this is that your domain doesn't have just one reputation. Each receiver creates their own assessment. This works like in real life where different people form varying opinions based on their interactions with you.
Gmail and other major ISPs tend to value domain reputation more than IP reputation. The reason makes sense - while IPs can change with different sending servers and providers, your sending domain remains constant, which makes it a better indicator of your sending history.
Note that both types of reputation combine to shape your overall sender reputation, much like your payment history and credit utilization shape your credit score.
Which factors affect sender reputation?
Let's look at what can make or break our email sender reputation. A good understanding of these elements helps us keep a healthy sending profile and deliver emails better.
1. Spam complaints
Recipients who mark our emails as spam send a strong negative signal to ISPs. Our spam complaint rate needs to stay below 0.1% to deliver emails effectively. This is a big deal as it means that if we go over 0.3%, major providers like Google might block our emails.
2. Spam traps
Special email addresses catch poor sending practices. Here are the three main types we deal with:
- Pristine traps: Never used for legitimate email
- Recycled traps: Former valid addresses repurposed as traps
- Typo traps: Common misspellings of email domains
3. Bounce rates
Our sender reputation depends on bounce rates. A well-managed, permission-based list should see bounce rates of 2% or less for each email campaign. ISPs see high bounce rates as a sign of poor list quality and might restrict delivery.
4. Sending history
Our sending patterns affect our reputation a lot. ISPs look at our email volume and frequency to determine if we're trustworthy. Our reputation can suffer if we suddenly increase sending volume or show inconsistent patterns.
5. Engagement
Engagement metrics are vital indicators of our sender reputation. ISPs keep track of:
- Open rates
- Click-through rates
- Reply rates
- Time spent reading emails
- Email folder movements by recipients
6. Unsubscribe rates
We want to keep unsubscribe rates below 0.5%. High unsubscribe rates tell ISPs that recipients might not find our content relevant, which hurts our sender reputation. Unsubscribe rates above 1% often warn us about upcoming spam complaints.
How to check your sender reputation
Email sender reputation monitoring plays a vital role to maintain healthy deliverability rates. We found four powerful tools that help us track and improve our sending reputation.
1. Sender Score
Sender Score gives us a numerical rating from 0 to 100, much like a credit score for our email sending practices. A score above 80 shows excellent reputation and proves we follow email marketing best practices. This tool helps us:
- Track IP reputation changes
- Monitor bounce rates
- Identify potential blocklist issues
- Compare our performance to global email senders
2. Talos Intelligence
Talos Intelligence gives a detailed look into our IP and domain reputation. The platform uses sophisticated security modeling to create granular reputation scores from -10 to +10. Talos breaks down sender reputation into three levels:
- Good: Little or no threat activity observed
- Neutral: Within acceptable parameters but may need monitoring
- Poor: Problematic level of threat activity detected
3. Google Postmaster Tools
Google Postmaster Tools are a great way to get insights specifically for emails sent to Gmail users. The platform shows detailed information about:
- Spam rates
- Domain reputation
- IP reputation
- Authentication results
- Delivery errors
4. Send Forensics
Send Forensics helps us with detailed deliverability analysis. This platform includes advanced features such as:
- Immediate spam testing powered by machine learning
- Detailed reputation dashboards
- Infrastructure monitoring with 24/7 alerts
- Integration with multiple Email Service Providers
The platform helps us spot potential spam triggers and fix deliverability issues before they affect our email campaigns. We like how it makes use of information from multiple sources, including Google Postmaster Tools and Microsoft SNDS.
Regular monitoring of our sender reputation through these tools lets us quickly spot and fix any issues that affect our email deliverability. This proactive approach ensures our messages reach our subscribers' inboxes consistently.

How to improve sender reputation
You need a smart plan to take control of your email sender reputation. Let me show you proven ways to boost your reputation and get better deliverability.
Authenticate your domain
Your sending domain needs proper authentication. Think of it as your email's digital ID card. You should implement these three vital protocols:
- SPF (Sender Policy Framework) to verify your sending sources
- DKIM (DomainKeys Identified Mail) to ensure email integrity
- DMARC (Domain-based Message Authentication) to protect against spoofing
Grow your list organically
The right way to build your email list is vital to maintain a strong sender reputation. Double opt-in leads to much better engagement metrics and fewer spam complaints. Never buy email lists - this can trigger spam traps and hurt your sender reputation.
Clean your list on a regular basis
Your sender reputation depends on regular list maintenance. You should clean your email lists every three months. Remove invalid addresses and unengaged subscribers to keep bounce rates under 2%. This helps you avoid spam traps and maintains healthy engagement metrics.
Work on improving engagement
Your sender reputation relies heavily on engagement. Here's what you need to focus on:
Personalization: Tailor your content to your subscribers' interests and behaviors to get more opens.
Consistent sending: Keep a regular schedule instead of random bursts. ISPs might flag sudden volume increases as suspicious .
Preference management: Let subscribers control their email settings. An easy unsubscribe option prevents spam complaints because frustrated subscribers won't need to mark your emails as spam.
Monitoring metrics: Track your engagement rates with tools like Google Postmaster Tools to spot and fix problems early.
These strategies build the foundation for excellent deliverability. Note that your sender reputation needs constant care and attention, just like a credit score.
