Nina argues that list quality matters more than list size. A large list filled with inactive or disposable addresses will hurt your results. It can reduce engagement rates and damage your sender reputation. eCommerce brands should focus on attracting subscribers who genuinely want to hear from them and are likely to become customers.Clean Your List Before Problems Affect DeliverabilityEmail list cleaning should happen before deliverability issues appear. Nina highlights three key moments to review list quality: during platform migrations, after aggressive list-building campaigns, and before re-engagement sends. These activities often introduce low-quality or inactive contacts into your database. Sending to those contacts can trigger spam filters and lower inbox placement rates. Regular list cleaning helps ensure your best customers continue receiving your emails.Use Engagement Data to Protect Future PerformanceMailbox providers are paying more attention to how subscribers interact with your emails. If too many people ignore your messages, future campaigns may struggle to reach the inbox. That makes subscriber engagement a critical metric for every eCommerce marketer. Nina recommends automating re-engagement campaigns and removing contacts who no longer interact with your brand. A smaller but highly engaged audience will often generate better results than a much larger inactive list.Takeaways:Rethink your email list: it’s not just a number, it’s an audience you’re responsible for. Focus on building genuine relationships, not just growing for growth’s sake. Real engagement beats noise every time.Email deliverability isn’t just technical; marketers have more control than they think. Cleaning your list regularly helps boost reputation and ensures your messages reach actual people, not empty inboxes.Removing disengaged and invalid contacts is crucial. Don’t pay for contacts who don’t care, and protect your sender reputation by keeping your list healthy. Quality over quantity wins in the inbox.Big campaigns? Always clean your list. Whether you’re migrating to a new platform, running giveaways, or reactivating dormant lists, start with quality data so you don’t damage your sender reputation.Automate your list hygiene: use double opt-in, re-engagement campaigns, and quality checkers. The cleaner your data, the better your results, and the truer your email stats and campaign insights.Find the notes here: https://keepopt.com/312Try Klaviyo for free >>> https://keepopt.com/klaviyo **** Get all the links and resources we mention & join our email list at https://keepopt.com Love the show?
