When it comes to improving email marketing for retention, the experts are split into two distinct camps. The debate is between obsessing over the foundational health of your entire email program versus surgically optimizing a few key, high-impact automated moments. Where you start depends on what your brand needs most right now.
Camp A: The Foundationalists
This group argues that no amount of clever automation can save a list that’s suffering from poor deliverability or unengaging content. Their focus is on the long-term health and trust of the subscriber relationship. On an episode of Ecommerce Conversations, Listrak CEO Ross Kramer makes a strong case for actively managing dormant email lists instead of just letting them decay, which is a classic foundationalist view. It’s not about one campaign, but the overall health of the asset. Similarly, Andrew Faris of Ecommerce Playbook constantly emphasizes the long-term value of an email list, urging brands not to give up on subscribers who don't buy immediately. This camp believes retention is the cumulative result of consistent value, excellent list hygiene, and smart segmentation. The core idea is that if you do the fundamentals well, you prevent subscribers from churning out in the first place, making aggressive claw-back tactics less necessary. Their metric for success is sustained engagement across the entire list, not just conversion spikes from a few automations.
Camp B: The Automation Optimizers
This camp believes that outsized gains come from perfecting specific, high-leverage touchpoints in the customer journey, particularly those that can be fully automated. Andrew Christison, speaking on the Up Arrow Podcast, laid out a powerful framework that starts with the welcome series. He argues this is the most critical moment, as it sets the tone for the entire customer relationship. Braxton Manley, also on Up Arrow Podcast, doubles down on this, stating the best way to increase retention performance is by perfecting the pop-up and immediately making subscribers excited to engage. This group focuses intensely on getting the tech stack right, collecting zero-party data from the very first interaction, and building powerful, personalized email automation. They argue that by nailing the welcome series, abandoned cart sequences, and post-purchase follow-ups, you can build enough momentum and revenue to fund all other marketing. Their focus is on maximizing the ROI of each subscriber from day one.
Personally, I believe Camp B offers the more practical starting point, but it’s ultimately an incomplete strategy without the wisdom of Camp A. You should absolutely begin by auditing and relentlessly optimizing your core automations. The welcome series and abandoned cart flow are your lowest-hanging fruit and highest-impact opportunities. Andrew Christison’s retention framework is the perfect place to start because it provides immediate, measurable results. Those quick wins are what build the case for deeper investment in the email channel.
However, once those automations are humming, your focus must shift to the foundational health that Camp A champions. A high-performing welcome series is great, but it won’t sustain you if your regular emails start landing in spam or if your engagement drops off after the first month. Your strategy should mature. If you’re just starting out or your retention is struggling, be an Automation Optimizer. Fix your welcome series and post-purchase flows this week. If you’re a more mature brand with solid automations, it’s time to become a Foundationalist. Dive into your email deliverability, re-engage your sleepy subscribers, and run a proper audit on segmenting customer lists to ensure your program has staying power.
