Why Quality Email Subscribers Matter More Than Quantity

This is part of our Quick Tip series of shorter, single-focused articles. This particular one was inspired by a LinkedIn post by Casey Hill.
Growing your email subscriber list is always a win, right? Especially with handy tools like Substack, ConvertKit, or Beehiiv recommending your content. But what if I told you that it might not be all it's cracked up to be?
Casey has talked with many creators, including Brendan Hufford (you can catch the clip below), who shared their experiences with these recommendation features. The consensus? These tools can bring in subscribers, but often, they come with a catch: low-quality leads, spam complaints, and non-engaged readers.
This points to a bigger problem in email marketing. The best newsletters don't just aim to grow their subscriber list—they focus on attracting the right subscribers. It’s about quality over quantity. They make sure their content only reaches people who truly want to hear from them.
The problem with low-quality leads
Using recommendation tools might boost your numbers, but not all subscribers are created equal. When your list is filled with people who aren't genuinely interested in your content, a few problems come up:
Low engagement: These subscribers are less likely to open your emails buy telemarketing data or click through your content, leading to poor engagement metrics.
Spam complaints: Non-engaged subscribers might mark your emails as spam, damaging your sender reputation and deliverability rates.
High unsubscribe rates: A significant portion of these new subscribers may quickly unsubscribe, which, while not directly harmful, indicates a mismatch between your content and your audience.
The importance of a clean email list
Maintaining a clean email list is crucial. The best newsletters actively work to ensure their list is full of engaged readers. They don’t shy away from unsubscribes—in fact, they welcome them. Why? Because an unsubscribe is better than a spam complaint, and it helps keep your list healthy and engaged.
Here are some strategies to keep your email list clean:
Regularly purge inactive subscribers: If someone hasn’t engaged with your emails in a while, it might be time to let them go. This helps improve your engagement rates and ensures your content reaches those who care about it.
Encourage unsubscribes: Make it easy for people to unsubscribe if they’re no longer interested. This might seem counterintuitive, but it’s better to have a smaller, more engaged list than a large, disinterested one.
Segment your list: Use segmentation to send more relevant content to different groups of subscribers. This ensures each email is more likely to be of interest to its recipient, boosting engagement.
