It is important to ensure that your list is clean and healthy so that your email marketing is efficient. List hygiene contributes to: increased engagement, ensures that only relevant audiences receive your messages, and maintains your sender score. In this article, we will go through the steps needed to keep the status of an email list healthy.

Why It Is Important to Maintain a Clean List

• Enhancing Deliverability: This implies that when your list is clean your emails are not rejected as spam or bounce back to you. Open rates and spam complaints are some of the things that ISPs use in determining how you handle emails. Besides, the reduction in the number of bounces and spam complaints will also boost the overall success of your campaigns.
  
• Boosting Engagement: Open and click-through rates rise when the target market has been defined and reached. Thus, it will be easier for your subscribers to engage with the content if the emails you send them are related to their interests.
  
• Preserving Sender Reputation: Other things that ISPs take into consideration include spam complaints and engagement rates as far as the sender's reputation is concerned. Having a good sender reputation means that subsequent e-mails get delivered to the recipient’s mailbox and not the spam folder.

Some guidelines on Maintaining Your Email List

1. Remove Dormant Subscribers

You should ensure that you clean up your email subscriber list by removing people who are not active and have not opened your emails for the past few weeks. Here's how to do it:

• Establish a Benchmark: Choose a period of inactivity, say six months and then categorize the subscribers as inactive subscribers. At this time, the people who have not clicked or opened the emails sent by you can be considered inactive subscribers.
  
• Re-engagement Campaign: Before eliminating the clients, it is always advisable to try a reactivation campaign to bring back the dormant clients. To draw their attention again, it is possible to send them several more emails with special offers, prices, etc.
  
• Unsubscribe or Delete: If they do not respond, it is rather preferable to take them from your list. They must not be kept in your database as they hamper your sender reputation and engagement rates.

2. Validate Email Addresses

Use checkers to confirm the appropriate format and existence of the email addresses. If you want to delete some bad addresses you can also use other techniques such as using email validation with regex. Here's how:

• Validation Tools: To verify the authenticity of the email addresses in your list, you can use credible email validation services such as EmailListVerify, NeverBounce, or ZeroBounce.
  
• Frequent Inspections: It is recommended that you carry out the validation checks frequently to maintain a clean list. This makes it easy to delete or suspend any wrong or inactive email address that has been entered.

3. Segment Your Mail List

One of the ways of increasing the open rate is through segmenting the list and sending different messages to different consumers. Consider these strategies:

• Demographic Segmentation: People can be grouped according to age, sex, employment status, geographical location, or any other manner. This makes it easier to relay special messages to certain segments of the population at any given time.
  
• Behavioral Segmentation: Divide the population according to its email interaction level, prior contacts, purchase history, and website traffic. This enables you to provide the subscriber with additional information concerning their preferences and engagement.

• Confirmation Email: Make it a point that the subscription messages that will be sent to the new subscribers contain links to confirm the subscription. For this, it is required to click the link to confirm its subscription.
  
• Engaged Subscribers: This is because you are likely to get a response from the interested and engaged subscribers in your list.

5. Regularly Update Preferences

Allow users to edit their current interests and add new ones. Thus, your emails will be useful for the audience, and the list will stay active and interested in receiving further messages. Consider the following:

• Preference Center: Create a preference center where the subscriber can update their contact information, delivery preferences, and interests. They now have better control over the type and quantity of mail that gets into their inboxes.
  
• Frequent Reminders: Therefore, inform the subscribers to update their preferences once in a while. You can achieve this, for example, by sending a preference update e-mail notification and using the link to the preference center in your regular e-mails.
