Sender Reputation Score Explained

The sender Reputation Score is an industry-standard metric that measures the quality of an email sender’s reputation. A high score means that the sender is considered to be a trustworthy source of the email, while a low score indicates that the sender may be considered spammy or suspicious.

The sender reputation Score is based on a number of factors, including the number of complaints filed against the sender, the percentage of emails that are marked as spam, and the number of invalid addresses associated with the sender.

A high SRS indicates that the sender is more likely to be considered spam, while a low SRS means that the sender is less likely to be considered spam. In order to ensure that your emails are not marked as spam, it is important to keep your SRS score high. There are a few things you can do to improve your score, such as using a double opt-in list, sending relevant and targeted content, using a reliable email checker tool, and most importantly, avoiding purchasing email lists.

A sender reputation score is just the tip of the iceberg, there are other dew things you must know about to improve your relationship with the email service provider:

Domain reputation

This is the measure of how well a domain is liked by Email Service Providers (ESPs). A good domain reputation can help increase deliverability rates, while a bad reputation can lead to emails being sent to spam folders or not delivered at all.

A domain’s reputation is measured by its Sender Reputation Score (SRS). This score is calculated based on a number of factors, including the number of complaints filed against the domain, the percentage of emails that are marked as spam, and the bounce rate.

A high SRS indicates that a domain is trusted by ESPs and is more likely to have its emails delivered to inboxes. A low SRS, on the other hand, means that a domain is less trusted and its emails are more likely to be sent to spam folders.

IP reputation

Domain reputation is another deciding aspect that assemblies the IPs from the house address you are sending the emails from. Some Internet Service Providers (ISPs) use domain repute while others, like IP addresses, have a heavier impact on reputation scores for many mailboxes.

Content reputation

This is a less technical criterion than what is mentioned above. There are a lot of factors that go into building a good reputation for your content. Creating quality content is the first step, but you also need to make sure that your audience can find it easily and that it’s engaging enough to keep them coming back for more.

Building a good reputation takes time and effort, but it’s worth it in the end. Your audience will appreciate knowing that they can always count on you for high-quality content, and you’ll be able to reap the benefits of having a loyal following.

When it comes to building a good content reputation, it takes time and effort to get it where you want it to be. There’s no magic bullet or one-size-fits-all solution – it all depends on the type of content you’re producing, and how well you promote and distribute it.

To start with, make sure your content is high quality and brings tremendous value to your target audience. This is the most important part, as without this your efforts will be fruitless

Once you have great content, start promoting it through social media, email marketing, guest blogging, and any other channels you can think of.

It takes persistence and dedication to build a good content reputation, but it’s well worth the effort, and you’ll eventually start reaping big rewards from a community that you’ve built.

Monitor your sender’s reputation

Sender reputation is important because it is one of the main factors that ISPs use to determine whether or not to deliver your email to the inbox. A sender with a poor reputation is more likely to have their email sent to spam, or not delivered at all.

Monitoring your sender’s reputation can help you avoid deliverability issues and ensure that your email reaches the inbox. There are a few different ways to monitor your sender’s reputation, including using a third-party service or monitoring your own bounce rates manually.

The best way to get started is to make sure you’re only sending emails to people who have opted in to receive them. Second, keep your list clean by regularly removing inactive subscribers and bounced addresses. You can do that by using an email checker tool such as Email List Validation.

It’s also incredibly important to monitor your bounce rate, complaint rate, and mailing list health. Your bounce rate is a measure of how many of your emails are undeliverable, and should be less than 2%. Your complaint rate is the number of recipients who mark your email as spam and should be less than 0.1%.

By monitoring your sender’s reputation and taking steps to improve it, you can ensure that your emails are reaching the inboxes of your intended recipients.

Make sure you check the validity of your emails

Email lists can quickly become outdated if they are not regularly validated. Addresses on your list may become invalid for a variety of reasons, including people changing jobs or email providers, or simply typos when the address was first entered.

If you regularly validate your email list, you can be sure that the addresses on it are still active and that you are able to reach your intended audience. Additionally, validating your list can help to improve deliverability rates and ensure that your messages are not marked as spam. Thus, dramatically improving your sender’s reputation.

You can start validating your email list by using an email checker tool like Email List Validation.

Overall, there are many benefits to regularly validating your email list. By taking this simple step, you can ensure that your emails are reaching the people who want to receive them.

Reduce feedback loop complaints.

Feedback loops are set up so that when someone marks an email as spam, the sender is notified. This allows you to adjust your content and improve your deliverability. If you have a lot of feedback loop complaints, it can hurt your reputation and lead to your emails being blocked.

There are a few things you can do to decrease feedback loop complaints. First, make sure that you’re only sending emails to people who have opted in to receive them. This may seem like a no-brainer, but it’s worth mentioning because it’s one of the most common causes of feedback loop complaints.

Second, take a look at your content and make sure it’s relevant and engaging. If people are finding your emails uninteresting or irrelevant, they’re more likely to mark them as spam. Thus, your sender’s reputation will take an increasing amount of damage.

Finally, keep an eye on your bounce rate and make sure that you’re not sending too many emails to invalid addresses. If your bounce rate is high, it could trigger a feedback loop complaint from your email provider.

Observe open and click rates.

If you’ve been involved in email marketing lately, then you know how important it is to have a high open and click-through rate. After all, what’s the point of sending emails if no one is reading them? That’s why it’s so important to monitor your open and click rates.


Here are a few reasons why you might want to start monitoring your open and click-through rates.

  • It allows you to gauge the effectiveness of your subject lines. The subject line is often the make-or-break factor when it comes to whether or not someone will open your email. If you see that your open rates are low, then it’s time to start experimenting with different subject lines.
  • It helps you determine which content is resonating with your audience. If you see that people are clicking on certain links or opening certain attachments, then you know that that type of content is resonating with them.

Keep an eye on unsubscribe and bounce rates.

Bounce rates and unsubscribe rates are two of the most important metrics for anyone who is thinking of getting advanced at email marketing.

If your bounce rate is high, it means that your emails are not being delivered to your subscribers. If your unsubscribe rate is high, it means that people are not interested in your content.

Monitoring these metrics will help you improve your email deliverability and make sure that people are actually seeing your content.

Monitoring these metrics meticulously can significantly improve your email deliverability.

If you see that your bounce rate is high, you can take steps to improve email deliverability, such as using a different email provider or changing the way you format your emails. or even consider cleaning out your entire email list from inactive or invalid subscribers who are not particularly engaged with your emails.

You can easily do that by using an email checker software like Email List Validation today and you can verify up to 100 emails completely for free without entering your credit card information.

Use a double-opt-in

One of the most important aspects of any email marketing strategy is the use of a double opt-in process for your subscribers.

By requiring potential subscribers to confirm their email addresses twice, you can be sure that they actually want to receive communications from you. This helps to improve both the quality and quantity of your email list, which in turn can lead to better email deliverability and improved open and click-through rates and maintain an incredible sender reputation.

There are a number of reasons why using a double opt-in is beneficial for your email sender provider. First, it helps to ensure that only people who actually want to receive your emails are added to your list. This reduces the chances of your emails being marked as spam by potential subscribers who never intended to sign up for them in the first place.

Monitor hard bounce rates.

Normally, your email sender provider should have tools in place to help you monitor your hard bounce rates. By doing so, you can ensure that your messages are getting through to your recipients and avoid potential deliverability issues.

There are a number of reasons why you might have a high hard bounce rate. Perhaps you’re using an outdated email list, in that case, we recommended that you take the initiative and clean up your email list using a reliable email checker tool.

Or maybe you’re sending it to too many invalid addresses. Whatever the reason, it’s important to identify the problem and take steps to fix it.

If you’re not monitoring your hard bounce rate, you could be missing out on important insights into the effectiveness of your email campaigns. So make sure to keep an eye on this metric and take action if necessary.
