How to Improve Sender Reputation Score/IP

Published Date: 9/26/2024

Email marketing is one of the most powerful tools for engaging with customers, but its success depends on one key metric: how your sender’s reputation score may affect you. This score is your reputation for your Bulk Email and it is evaluated by Internet Service Providers (ISPs) to check if your emails are ‘good’ emails or ‘junk’ mail. However, poor performance is likely to lead to emails being delivered directly to the spam buttons, or simply rejected.

The sender reputation score is a significant factor that determines the ability of your emails to reach your recipients’ inboxes. Here, we will discuss what impacts the score and the actionable tips you can take to improve it to deliver your messages to the primary inbox.

What is the Sender Reputation Score?

Your sender reputation score is therefore a rating that ISPs apply to your email-sending domain or IP address. This depends on several factors such as the frequency of opening the emails by the recipients, the quality of the mailing list, and whether your emails get to the spam folder or not. This will depend on the score you achieve, the higher the score the more chances of your email reaching your recipients’ Inbox as opposed to the Spam folder.

Sender's reputation can be associated with

IP reputation: Dependent on the IP address of the server that the recipient receives your emails.
Domain reputation: Bounded to the domain of emails that are sent.

Bettering both domain and IP reputation is one of the ways through which the success of business email marketing can be enhanced.

Why is the Sender’s Reputation Important?

Having a good sender reputation has a direct positive correlation with the deliverability of specific emails. Studies that have been done on the topic of email marketing reveal that as much as 21% of marketing emails do not ever reach the recipient’s inbox. Hence when you enhance sender reputation, you make sure that many of your emails are delivered to the target recipients thereby enhancing the performance of your campaigns and hence enhancing engagement.

Steps to Improve Your Sender Reputation Score/IP

1. Clean and Maintain Your Email List Regularly

That’s why the quality of your e-mail list is one of the key factors that define the sender’s reputation. I have discovered that sending emails to such dead addresses or users who have not opened the messages will raise your bounce rates plus spark off spam complaints to the technological level. To avoid these issues, regularly clean your email list by:

Erasing hard bounces (that is the list of e-mail addresses that lead to the delivery failure).
Mailing lists cleaning – banning IDs of those who have not opened your emails for quite a long time.
Targeting relevant topics that may appeal to your users hence targeting persons most likely to re-engage in the list.

Instead, use the following 3 email list brokers to verify the email list before introducing them into the system, ZeroBounce, NeverBounce, and Hunter.

2. Authenticate Your Emails

Authentication assists ISPs to cope with the fact that your emails are original and come from a genuine source. It is essential to implement secure authentication measures that would help improve the organization’s image, as well as assess reputation. Three key authentication methods include:

SPF (Sender Policy Framework): Prevents entry of unauthorized IP Addresses from sending emails to your domain.
DKIM (DomainKeys Identified Mail): Appends a digital signature to every email sent regarding the composition to ensure it has not been tampered with.
DMARC (Domain-based Message Authentication, Reporting & Conformance): Integrates SPF and DKIM so you can get greater control over ‘what happens when’ your emails fail these checks, and gives you lots of these events.

Implementing these measures is also effective in preventing your domain from getting spoofed and increasing the ISP’s confidence in your emails.

3. Send Emails Consistently

This is dangerous because receiving parties are often large ISPs and your e-mail campaign could be suddenly marked spam. Sending frequent emails to the recipients also makes a way of proving that you are a genuine sender in the marketplace. If you want to pump up the volume of your emails, it is recommended that it should be done progressively to prevent ISPs from flagging your account.

In case you are changing your IP address, you can use IP warming which is a process that puts your new IP address gradually to ISPs taking small lots of emails and then gradually adding the lots. This gradual method is also beneficial in building a good reputation for the new IP address that you want to use.

4. Avoid Spammy Content

Isps can predict spam-like messages through algorithms. If your emails have such features as a catchy but utterly false subject line, many excited exclamations or any other symbols, or some words like ‘free’, ‘for a limited time’, or ‘act now’, your emails will be considered spam.

To avoid this:

Always compose more appropriate subject lines that should match with the content material of the e-mail.
Do not capitalize unnecessarily put numerous exclamation marks or exaggerate in your messages.
Remember to have approximately equal amount of text and illustrations and do not put too many links.

The aim here is to be useful and to maintain relevance to what you promised to your subscribers.

5. Encourage Engagement

A second feature is that high engagement rates are a very clear indication to ISPs that the recipients of the emails value the emails and therefore they should allow them through. Engagement is defined as activities that subscribers take within your message such as opening the mail, clicking on the links, responding, or forwarding it. Here’s how you can boost engagement:

Personalize your emails: Use the recipient’s name and try to write the message as suitably as possible according to the interests of the recipient.
Segment your list: Deliver emails to different clients according to their previous actions or some other parameters they set.
Create compelling CTAs (Call to Action): Always ensure your emails are placed in a way that compels the readers to do something such as clicking a link, purchasing something, or attending a given event.

Click-through rates, response rates, open rates, and the like are all part of increasing or building the sender's reputation score.

6. Honor Opt-Out Requests

There should be an option of unsubscribing for the recipients from the emails received in the mailing list. Omitting an obvious link to unsubscribe will lead to spam complaints hence damaging your reputation. If a person decides not to be part of this process anymore, respect this decision, and do not send further messages, complaints will follow.

Further, one can implement a preference center that allows the subscribers to control the type and frequency of the emails sent to them this will reduce on number of people who unsubscribe from the list.

7. Monitor Your Sender Reputation

This is crucial because, by tracking your sender’s reputation score, you will note any issues as they arise so that you can work on them. There are several tools you can use to keep an eye on your reputation:

Google Postmaster Tools: Get an understanding of how Gmail is handling your emails.
Sender Score by Validity: Its score ranges from 0 to 100 which rates your sender’s reputation.
Microsoft SNDS: This reveals how your email communication is managed by Microsoft-related areas such as Outlook or Hotmail.

Taking time to check these tools will give you an insight into how ISPs perceive your emails and always be on the lookout for problems before they occur in your campaigns.

Conclusion

It is essential to ensure that you clean your email list, verify your identity, maintain consistent sending rates, and encourage responses if you want to be a good sender and receive higher delivery rates into inboxes.
