The importance of subscriber data management in email marketing

It’s not rare for marketers to come across statements such as that social media has eclipsed email marketing as the most effective channel for reaching and engaging audiences. The reality, however, tells a different story. 

Despite the meteoric rise of social media, email marketing remains a powerhouse, delivering one of the highest ROIs in the digital marketing world. An impressive $36 for every $1 spent, to be exact. However, the success of email marketing hinges on one important element — effective subscriber data management.

Why subscriber data management is important

1.   Targeted campaigns and personalization

Having accurate and detailed subscriber data in your hands opens the door for personalized messaging, which is considered one of the best email marketing strategies. For example, if you were to personalize your email campaigns subject line, it would be 26% more likely that your audience will open that message.

2.   Improved deliverability

What’s the point of crafting amazing email campaigns if they won’t be delivered to your audience? Reputable email service providers (ESPs) monitor bounce rates, spam complaints, and engagement levels to determine your sender reputation. A poor sender reputation can lead to your emails being marked as spam or not delivered at all. Regularly conducting an email deliverability test, cleaning your list, removing inactive/invalid addresses, and maintaining a healthy sender reputation are crucial to ensure success.

3.   Regulatory compliance

The introduction of the General Data Protection Regulation (GDPR) and other data protection laws has made compliance a non-negotiable aspect of email marketing. Mishandling subscriber data can lead to fines and damage to your brand’s reputation. By properly managing your subscriber data, you’ll be protecting both your subscribers and your business.

Best practices for managing subscriber data

1.   Obtain explicit consent

The foundation of a GDPR-compliant subscriber database is explicit consent. You have to make sure that subscribers actively opt-in to receive emails from you. Be clear and straightforward on your sign-up forms — potential subscribers need to know exactly what they’re opting-in for. And to really ensure the explicit consent — have your new subscribers confirm their subscription via a follow-up email.

2.   Regularly clean your list

A big part of email list management is regular list cleaning. In this process you remove inactive subscribers, hard bounces, and invalid email addresses from your list. Of course, beforehand it’s recommended to define inactivity thresholds (e.g., not opening or clicking any emails in six months) and send re-engagement email campaigns to try and win them back. If they remain inactive, it’s time to let them go.

3.   Maintain data accuracy

Encourage subscribers to periodically update their information. Best way to do that is to include a link to manage subscription preferences in every email. This allows subscribers to update their email addresses, interests, and other personal information, so your data remains accurate and up-to-date.

4.   Segmentation and personalization

In the age of cookieless marketing, first-party data is your best friend when it comes to personalization. Collect it to segment your audience into different groups based on demographics, behavior, purchase history, and engagement levels. The more segmented your list, the more personalized your emails can be. 

5.   Transparency and communication

Be transparent with your subscribers about how you collect, store, and use their data. Provide clear privacy policies and make them easily accessible. If you make any changes to how you handle subscriber data, communicate these changes timely and transparently. You want your subscribers to trust you.

What’s in it for you

A proper email list management may seem like a lot of work at first, but with time it becomes a second nature. These practices are here to protect you as much as they are protecting your subscribers. 

By adhering to best practices you’ll soon see the benefits yourself: 

1.   Higher engagement rates

When your list is free from inactive subscribers, you’ll automatically see more accurate results in your campaign reports, like higher engagement rates. 

2.   Better ROI

You’re ensuring that your messages are reaching those who are interested in what you have to say (and sell). This translates into higher conversion rates and a better ROI.

3.   Reputation and deliverability

By adhering to best practices, you protect your sender reputation, which ensures that your emails are delivered to the inbox rather than the spam folder.

4.   Regulatory compliance

By showing your subscribers that you follow regulatory compliance, you’re not only avoiding legal repercussions, but also building trust. 

5.   Informed decision making

When you properly manage your subscriber data, it can provide valuable insights into their behavior and preferences. These insights can influence your broader marketing strategies in the future.

Wrap up

In the competitive landscape of digital marketing, effective subscriber data management is not just a best practice — it’s a necessity. Investing time and resources into managing your subscriber data pays off, as you start to see higher engagement rates and ROI, and your sender reputation becomes pristine.
