Below the surface of spam filters and algorithmically generated search results lies a critical component of emailing: your sender reputation. 

 

This is perhaps one of the least discussed topics among both casual mailing list senders and seasoned professionals alike. Unfortunately, many marketers and business owners don’t recognize its importance until they begin to experience deliverability issues in their emails. 

 

In this blog post, we'll discuss how you can manage your sender reputation well and maintain good emailing practices to ensure maximum inbox placement for all that hard work you put into crafting your messages!

 

 

What is email sender reputation?

 

Email sender reputation refers to the overall perception that email service providers (ESPs) and Internet Service Providers (ISPs) have of a sender's email practices. It is determined by various factors such as the quality of the content, engagement rates, and the sender's compliance with anti-spam laws and regulations.

 

An email sender's reputation plays a crucial role in determining the success of their email marketing campaigns. If a sender has a good reputation, their emails are more likely to reach their intended recipients' inboxes. However, if their reputation is poor, their emails may be filtered as spam, blocked, or even blacklisted.

 

ESPs and ISPs use various tools to monitor sender reputation, such as spam filters, blacklists, and whitelists. They also track metrics such as bounce rates, spam complaints, and engagement rates to evaluate the quality of the sender's email campaigns.

 

To maintain a good email sender reputation, businesses should focus on providing relevant, engaging, and valuable content to their subscribers, ensuring that their email lists are clean and up-to-date, and following best practices for email marketing. By maintaining a good sender reputation, businesses can ensure that their emails reach their subscribers' inboxes and achieve the desired results.

 

 

What factors can influence the evaluation of the sender's reputation?

 

◾ Spam complaints: If a high percentage of recipients mark emails as spam or junk, this can negatively impact the sender's reputation score.

 

◾ Bounce rates: A high rate of undeliverable emails can indicate a poor quality email list, which can lead to a lower reputation score.

 

◾ Engagement rates: If subscribers regularly open, click, and interact with emails, this can indicate a positive reputation score.

 

◾ Sender authentication: Using authentication protocols such as DKIM, SPF, and DMARC can help verify the sender's identity and prevent fraudulent emails, which can improve reputation scores.

 

◾ Content quality: Emails that contain spammy, deceptive, or irrelevant content can lead to lower reputation scores.

 

◾ List hygiene: Regularly cleaning and maintaining email lists, removing inactive or unengaged subscribers, and obtaining explicit consent from subscribers can improve reputation scores.

 

◾ Compliance with anti-spam laws: Following anti-spam laws and regulations, such as the CAN-SPAM Act in the United States, can help prevent spam complaints and improve reputation scores.

 

 

IP reputation vs Domain reputation. What's the difference?

 

IP reputation and domain reputation are two distinct factors that can affect email deliverability and sender reputation.

 

IP reputation refers to the reputation score of the IP address used to send emails. This score is based on factors such as the volume and quality of emails sent, the level of engagement from recipients, the presence of spam traps or other indicators of spam activity, and whether the IP address has been blacklisted by email service providers. A poor IP reputation can lead to emails being blocked or sent to spam folders, even if the content is legitimate and relevant to the recipient.

 

Domain reputation, on the other hand, refers to the reputation score of the sender's domain name. This score is based on similar factors as IP reputation, but focuses on the overall reputation of the sender's domain rather than the specific IP address. This can be influenced by factors such as the sender's email authentication practices, the quality of email list management, and the level of engagement and responsiveness of subscribers.

 

Both IP reputation and domain reputation are important factors in email deliverability and sender reputation. A sender with a good reputation for both their IP address and domain is more likely to have their emails delivered to the recipient's inbox, while a poor reputation can result in emails being blocked or filtered as spam.

 

It's important for senders to monitor both their IP and domain reputation, and take steps to maintain a positive reputation score through best practices such as list hygiene, email authentication, and relevant and engaging content.

If your emails are consistently being blocked or sent to spam folders, it's possible that your IP address or domain has been added to a blacklist. You can use tools such as MXToolbox and Spamhaus to check if your IP address or domain is listed on any blacklists.

 

4. Monitor email engagement metrics.

 

High engagement metrics, such as open rates, click-through rates, and low bounce rates, are indicative of a good sender reputation. Monitor these metrics over time to identify trends and areas for improvement.

 

 

How to improve sender reputation?

 

Improving sender reputation involves implementing several best practices that are designed to increase the likelihood that your emails will be delivered to your subscribers' inboxes and not marked as spam.

 

Step 1. Use a professional email address.

 

✔ Use an email address with your own domain: Using an email address with your own domain, such as yourname@yourcompany.com, helps to establish your credibility and legitimacy as a sender. It also makes it easier for subscribers to recognize your brand and remember your email address.

 

✔ Avoid using free email services: Avoid using free email services such as Gmail, Yahoo, or Hotmail, for your business email address. These free email services are commonly used by spammers and are less likely to be trusted by subscribers and email service providers.

 

✔ Use a consistent email address: Use a consistent email address across all your email communications. This helps subscribers to recognize your brand and ensures that your emails are not mistaken for spam.

 

✔ Keep your email address short and simple: Use a short and simple email address that is easy to read and remember. Avoid using special characters or numbers that can make your email address look spammy.

 

 

Step 2: Collect quality emails

 

✔ Use double opt-in: Double opt-in requires subscribers to confirm their email address by clicking a link in a confirmation email. This helps to ensure that the email address is valid and that the subscriber actually wants to receive your emails.

 

✔ Offer something of value: Offer a lead magnet or other incentive in exchange for subscribing to your email list. This can be a free e-book, exclusive content, or a discount code.

 

✔ Use a reputable email service provider: Use an email service provider that is known for its high deliverability rates and has measures in place to prevent spam. Examples include Mailchimp, Constant Contact, and Campaign Monitor.

 

✔ Avoid purchasing email lists: Purchasing email lists can result in a high number of invalid or spam email addresses, which can hurt your sender reputation.

 

✔ Regularly clean up your email list: Remove inactive or invalid email addresses from your list on a regular basis. This helps to maintain a healthy list and reduces the likelihood of your emails being marked as spam.

 

 

Step 3. Develop a warm up email strategy

 

Developing an warm-up email strategy is an important step in improving your sender reputation and ensuring that your emails are delivered to your subscribers' inboxes. 

 

Email warm-up is the process of gradually increasing the volume and frequency of your email sends to build trust with ISPs (Internet Service Providers) and improve your sender reputation.

 

Doing it manually is long and difficult, so it is best to use email deliverability services.

Step 4. Authenticate your emails

 

Email authentication helps to verify that your emails are coming from a trusted source and are not being spoofed or impersonated by spammers. Here are some ways to authenticate your emails:

 

✔ SPF (Sender Policy Framework): SPF is a type of email authentication that verifies that the IP address sending the email is authorized to send messages on behalf of the domain in the "From" field. SPF records are added to your domain's DNS settings.

 

✔ DKIM (DomainKeys Identified Mail): DKIM is a type of email authentication that adds a digital signature to your emails. This signature verifies that the email was sent by an authorized sender and that the email has not been tampered with in transit.

 

✔ DMARC (Domain-based Message Authentication, Reporting, and Conformance): DMARC is an email authentication protocol that builds on SPF and DKIM. It helps to ensure that emails are properly authenticated and provides a way for email service providers to report back to senders about any authentication failures.

Step 5. Provide valuable content.

 

✔ Know your audience: Understand who your subscribers are and what type of content they are interested in. Use this information to tailor your content to their interests and needs.

 

✔ Keep it relevant: Make sure that your content is relevant to your subscribers and their interests. Avoid sending emails that are not related to your subscribers' interests or needs.

 

✔ Provide valuable information: Offer valuable information that your subscribers can use to solve a problem or achieve a goal. This can include how-to guides, tips and tricks, or industry insights.

 

✔ Be concise: Keep your emails concise and to the point. Avoid using jargon or technical terms that your subscribers may not understand.

 

 

Step 6. Use visuals

 

✔ Use high-quality images: Use high-quality images that are relevant to your content and are visually appealing. Avoid using blurry or low-quality images that can make your emails look unprofessional.

 

✔ Optimize images for email: Optimize your images for email by compressing them and making sure that they are not too large. Large images can slow down the loading time of your emails, which can lead to subscribers losing interest and moving on.

 

✔ Use videos: Use videos to provide more engaging content and to help tell your story. Videos can be used to demonstrate a product or service, provide a behind-the-scenes look, or offer expert advice.

 

✔ Use infographics: Use infographics to help convey complex information in an easy-to-understand format. Infographics can be used to showcase statistics, explain a process, or provide a visual summary of a topic.

 

✔ Use alt tags: Use alt tags to describe your images in case they do not load properly. Alt tags also help subscribers who use screen readers to understand the content of your emails.

 

 

Step 7. Avoid spam triggers

 

✔ Using excessive punctuation or symbols: Avoid using excessive punctuation or symbols in your email subject lines or body. This can make your emails look spammy and can trigger spam filters.

 

✔ Using all caps: Avoid using all caps in your email subject lines or body. This can make your emails look like they are shouting and can trigger spam filters.

 

✔ Using spammy words: Avoid using spammy words in your email subject lines or body. These include words like "free", "discount", "cash", and "limited time offer". These words are commonly used by spammers and can trigger spam filters.

 

✔ Using deceptive subject lines: Avoid using deceptive subject lines that are not related to the content of your emails. This can mislead subscribers and can trigger spam filters.

 

✔ Using too many links: Avoid using too many links in your emails. This can make your emails look spammy and can trigger spam filters. Instead, use only relevant and necessary links.

 

Step 8. Check if you’re on any blacklists

 

✔ Use a blacklist checking tool like Warmy.io: There are many free tools available online that can check if your IP address or domain is on any blacklists. These tools can scan multiple blacklists at once and provide you with a report of any blacklists that your IP address or domain is on.

 

How to check IP reputation? IP blacklists

 

✔ Check individual blacklists: You can also check individual blacklists manually by visiting their websites and searching for your IP address or domain. If you find that your IP address or domain is on a blacklist, follow the steps provided by the blacklist to get delisted.

✔ Monitor your email deliverability: Even if you're not on any blacklists, it's important to monitor your email deliverability to ensure that your emails are being delivered to your subscribers' inboxes. Keep an eye on your email open rates, click-through rates, and bounce rates to ensure that your emails are engaging your subscribers and not being filtered as spam.

 

 

Step 9. Keep your email strategy fresh and engaging

 

✔ Segment your email list: Segment your email list based on subscriber behavior, demographics, or other relevant factors. This allows you to send targeted and personalized emails that are more likely to resonate with your subscribers.

 

✔ Experiment with different types of content: Try out different types of content in your emails, such as educational content, product updates, or industry news. This can help to keep your emails interesting and engaging.

 

✔ Use social proof: Use social proof, such as customer reviews or testimonials, in your emails to help build trust with your subscribers and increase the likelihood that they will engage with your emails.

 

✔ Include a clear call to action: Include a clear call to action in your emails to encourage subscribers to take action, such as making a purchase, signing up for a newsletter, or sharing your content on social media.

 

✔ Test and optimize: Test different elements of your email campaigns, such as subject lines, email copy, and images, to see what resonates best with your subscribers. Use this data to optimize your email campaigns over time.
